Your Game Has 3 Colorblind Modes — Here’s Which One You Actually Need

Why 88% of Colorblind Gamers Still Struggle Despite Built-In Modes

Eight percent of men are colorblind. In a lobby of twelve players, odds are at least one is navigating every match through a visual filter their hardware and game developers didn’t fully design for. A 2025 peer-reviewed study of 241 colorblind gamers found that 88% report meaningful difficulty while playing. The most affected genres? Military and action-adventure titles—exactly the competitive, reflex-heavy games where color-coded information matters most [3].

Most modern games now ship with three colorblind modes. The problem is that players pick one by trial and error, push the strength slider to maximum, and wonder why the game still looks wrong. Some modes genuinely help. Others make things worse—by remapping every color in the scene, not just the ones causing confusion.

This guide walks you through matching the right mode to your specific type of color vision deficiency, with specific slider values for the biggest titles, and what to adjust at the system level when the in-game toggle alone isn’t enough. Start with the hub: How to Optimize PC Game Settings for Better FPS covers the performance baseline your system needs before color calibration makes any difference.

Match Your Type to the Right Mode First

The three colorblind modes—Protanope, Deuteranope, and Tritanope—correspond directly to three types of cone deficiency in the eye. Picking the right one starts with identifying which cone type you’re working around.

The vast majority of colorblind players have red-green deficiency. According to the National Eye Institute, protanopia and deuteranopia both make red and green indistinguishable—but through different mechanisms. Deuteranomaly (mild green cone malfunction) affects roughly 6% of men. Protanomaly (mild red cone malfunction) affects about 0.54%. Tritanopia, which involves the blue cone, touches just 0.01% of the population [1][2].

If you’ve never had a formal diagnosis, start with Deuteranope—statistically, it’s the most likely match given how common deuteranomaly is. If that doesn’t clearly improve things, try Protanope next. Tritanope is the last to test unless you specifically notice blue-yellow confusion rather than red-green.

Before touching any menus: notice whether red elements look dark as well as confusing. That’s a specific protan signature—red light is perceived at reduced luminance, not just a shifted hue. If red looks wrong but not dim, deutan is more likely. This distinction matters for the system-level adjustments in Section 4.

Strength isn’t “more is always better.” A higher slider value applies a more aggressive full-scene color transformation. For mild anomalous forms (deuteranomaly, protanomaly), strength 4–6 often produces a more natural-looking image than maxing the slider, which can shift colors that weren’t previously a problem into new territory [7].

Why the Default Colorblind Mode Often Makes Things Worse

Most games apply colorblind settings as a full-screen color matrix—every pixel in the rendered frame goes through the same transform. The intention is correct: shift green-adjacent hues toward more distinguishable alternatives. The problem is scope.

When the entire scene gets remapped, grass, terrain, foliage, and UI elements all shift alongside the enemy outlines and health bars that actually needed changing. The result can push the genuinely confusing colors apart while pulling previously distinct colors closer together, creating new visual confusion the mode wasn’t designed to fix [4].

The better approach—used by Battlefield 4 and Destiny—remaps only gameplay-critical color channels: enemy outlines, minimap icons, team markers. The rest of the visual world stays intact. If the colorblind mode makes your game harder to read, not easier, follow this decision tree:

• Drop the strength to 2–3 rather than disabling the mode entirely. A subtle filter shifts the most extreme hue confusions without aggressively remapping everything.
• Try an adjacent mode type. Deuteranope and Protanope overlap significantly for mild red-green confusion—if one looks off, the other may be a better fit for your specific shift pattern.
• Use system-level settings alongside the mode rather than expecting the mode alone to do all the work. See Section 4 for what these are and how to configure them.

Game-by-Game Settings Guide

Fortnite

Access: Settings → Video tab → scroll to Colorblind Mode dropdown.

Three options: Protanope, Deuteranope, Tritanope. The strength slider runs 0–10 with 99 increments per mode. Recommended starting point: Protanope at strength 6. If you specifically struggle with green/red distinction (green looks red rather than red looking dark), try Deuteranope at 8–10 [5].

Test calibration on a Practice Island match before ranked play. Check that enemy outlines, the three build material colors (wood/brick/metal), and storm wall are all clearly distinct from each other. The storm wall’s bright blue is a useful calibration reference—if it reads clearly, your blue channel is intact.

One non-obvious note: some competitive players without colorblindness—including pro Tfue, who runs Deuteranope at 10—use these modes to increase enemy outline contrast in specific color environments. It’s not an exploit; every player can access it. The trade-off is that foliage and terrain gain a magenta/pink cast that some players find disorienting in dense bush cover.

Valorant

Access: Settings → General → Accessibility → Enemy Highlight Color.

Valorant’s implementation is cleaner than a full-screen filter—it remaps specifically the enemy highlight outline rather than every pixel. Four options: Red (default), Purple (Tritanopia), Yellow/Deuteranopia, Yellow/Protanopia. Both yellow options are noticeably more vibrant against most map backgrounds than red or purple [6].

Starting recommendation for red-green deficiency: either yellow option. The difference between the two yellow presets is subtle; pick the one that makes enemies feel most visually distinct on Ascent (bright surfaces) and Bind (dark surfaces).

Also under General → Accessibility: a separate full colorblind mode (3 types) for broader UI adjustment if the enemy highlight color alone isn’t enough.

System add-on that compounds well with Valorant’s settings: NVIDIA Digital Vibrance at 75–85% (NVIDIA Control Panel → Display → Adjust desktop color settings). This increases the saturation of all displayed colors, making adjacent hues on the red-green spectrum appear more distinct from each other.

Apex Legends

Access: Settings → Accessibility → Colorblind Mode: Protanopia, Deuteranopia, Tritanopia presets.

Apex separately controls damage number color accessibility under Settings → Gameplay → Damage Numbers—adjust this alongside your colorblind preset.

Critical known limitation (2025): Bloodhound and Crypto scan abilities render in default red regardless of which colorblind preset is active. The scan sweep and enemy highlights from these abilities don’t inherit the remapped color palette. This is a confirmed accessibility issue, not a misconfigured setting [8].

Workaround: rely on the scan sweep’s shape and audio cue rather than color to track Bloodhound’s highlighted enemies. When playing against Bloodhound, positional awareness and the distinct audio of the scan become your primary tracking tools instead of the visual highlight color.

Overwatch 2

Access: Options → Video → Color Blind Mode → Protanopia, Deuteranopia, Tritanopia with strength slider.

Map color palettes vary significantly in Overwatch 2. King’s Row and Eichenwalde (dark stone environments) generally work well at strength 5–7. Blizzard World and Busan (bright, high-saturation environments) may read better at 7–9. Set a baseline of 6 and test on two or three different maps before committing.

Finding Colorblind Settings in Any Game

Most titles bury these options under Accessibility, Video, or Display rather than a dedicated section. If searching in-menu fails, check PCGamingWiki’s confirmed colorblind mode list for your specific title. If the game has no native support, use NVIDIA or AMD driver-level color adjustments as a system-wide alternative. To understand what each video setting actually controls beyond colorblind options, PC Game Settings Explained covers every graphic option in detail.

Settings Beyond the Colorblind Toggle

The in-game mode is the starting point, not the complete solution. Two system-level adjustments consistently help regardless of which game you’re playing:

Digital Vibrance (NVIDIA) or Saturation (AMD)

NVIDIA Control Panel → Display → Adjust desktop color settings → Digital Vibrance. Default value: 50%. Recommended range: 70–85%.

Digital vibrance increases the saturation of all displayed colors, separating hues that appear similar at lower saturation levels. For protan and deutan players, colors on the red-green spectrum gain perceptual distance from each other. For tritan players, blue-yellow adjacencies sharpen. This setting applies globally—every application, not just games—which is why many competitive players use it regardless of whether they’re colorblind.

AMD users find the equivalent under AMD Software → Display → Color Settings → Saturation. Start at +20% above default and adjust from there. For detailed monitor-level calibration that compounds with this setting, see our guide to the best color settings for your gaming monitor.

Brightness and Luminance (Critical for Protan Types)

Protanopia and protanomaly cause red to appear darker than it actually is—this is a luminance shift, not just a hue shift. Colorblind modes remap the hue but don’t compensate for this perceived luminance drop. The result: red-derived information still appears dim even after the hue has been remapped to something theoretically more distinguishable [4].

Fix: raise in-game brightness 5–10% above default, or increase monitor luminance by one step. Test by looking at a red UI element after adjustment—it should feel naturally visible and present, not just a different shade of dark. Deutan players generally don’t need this brightness compensation; it’s specifically a protan accommodation.

FAQ

Is using colorblind mode a competitive advantage even without colorblindness?

Yes—and the game developers are aware of it. Some modes increase enemy outline contrast in specific color environments, which is why non-colorblind pros like Tfue run Deuteranope at strength 10. Every competitive title permits this; it’s an accessibility setting, not a cheat or exploit [5]. The trade-off is that visual elements beyond enemy highlights also shift, and some players find the remapped foliage or terrain creates its own distractions. Test across multiple map environments before committing to it in ranked play.

My colorblind mode makes the game look worse. What now?

Drop the strength slider to 2–3 first rather than disabling it entirely—a subtle filter fixes the most extreme confusions without aggressively remapping the whole scene. If it still looks wrong, try an adjacent mode type: Deuteranope and Protanope share significant overlap for mild red-green deficiency, and the one that doesn’t fit your specific shift pattern can make things worse. If neither mode type helps at any strength, turn the mode off and use digital vibrance plus brightness adjustments at the system level—these tend to produce more natural-looking improvements for players on the milder end of the spectrum.

I have anomalous trichromacy (mild version). Do I even need colorblind mode?

Not necessarily. Anomalous trichromacy shifts your color perception rather than eliminating a cone channel entirely. Full-strength colorblind modes are calibrated for complete dichromacy—they can look unnatural for mild deficiency because they’re overcompensating [7]. If you use a mode, try strength 3–5 rather than 7+. Many players with mild anomalous trichromacy find that digital vibrance at 70–80% alone produces more useful improvement than any full-screen colorblind filter, because it amplifies the distinction between adjacent hues without distorting the entire scene.

Verified on: April 2026. In-game option paths may shift with patches—settings found under Accessibility or Video tabs in each title.
