Test your color vision with Ishihara-style plates optimized for gamers.

## How to Use the Color Blindness Test

Click start to view the first plate. Each plate shows coloured dots with a number embedded; type or select the number you see, or choose 'No number' if you cannot make one out. Work through all plates at your own pace — there is no time limit. After the last plate the tool scores you and indicates whether your results suggest typical colour vision or a possible deficiency. Display calibration matters more than people expect, because the test relies on precise colour separation. Set your monitor to its default **sRGB** profile and turn off blue-light filters and night mode, which warp the very hues the plates depend on. Two technical settings can quietly skew results. First, **gamma** — the curve mapping signal to brightness; the sRGB and web standard is **gamma 2.2**, and a miscalibrated gamma shifts mid-tone colours enough to change which plates you can read. Second, **colour gamut** — many modern displays default to a wide **DCI-P3** gamut that over-saturates sRGB content, exaggerating reds and greens and making the test easier than reality. For an honest screening, use a standard sRGB mode at gamma 2.2, moderate brightness, and no glare.

## Why Color Vision Awareness Matters for Gamers

Many games lean heavily on colour to carry critical information: enemy nameplates, team indicators, minimap markers, status effects, and loot-rarity tiers are often distinguished by colour alone. A player with undiagnosed CVD may struggle to tell friend from foe or miss cues without knowing why. Knowing your specific type — **protan, deutan, or tritan** — lets you pick the matching colourblind mode in your games, which remaps problem hues into ones you can separate. The same knowledge has broad **design implications**: it is exactly why accessible design never relies on colour alone. Good UI pairs colour with a second channel — icons, shapes, text labels, or patterns — so a red/green distinction survives for the roughly 1-in-12 men who cannot see it. This is codified in the **WCAG** 'use of colour' guideline, and it is why well-designed dashboards add a shape to a red error dot and games let you recolour health bars. Beyond gaming, CVD affects reading maps and charts, judging fruit ripeness, and interpreting wiring or status LEDs. A quick screening is the first step: it tells you which accessibility settings to enable and helps you understand a difference you may have lived with unexamined.

## FAQ

### What is color blindness?

Color blindness (color vision deficiency) affects ~8% of men and ~0.5% of women. The most common type is red-green deficiency, making it hard to distinguish red and green shades.

### How does color blindness affect gaming?

Many games use red/green for enemy/friendly indicators. Color blind gamers may struggle with team identification, minimap colors, and loot rarity indicators.

### Can games be adjusted for color blindness?

Yes! Most modern games have color blind modes (Deuteranopia, Protanopia, Tritanopia settings). These remap problem colors to distinguishable alternatives.
