Color Blindness Test
Test your color vision with Ishihara-style plates optimized for gamers.
What Is a Color Blindness Test?
A color blindness test screens for color vision deficiency using Ishihara-style dot plates — circular images made of colored dots that form a number visible to people with normal color vision. If you have difficulty distinguishing certain colors, some numbers will be hard or impossible to see. Color vision deficiency affects roughly 8 percent of men and 0.5 percent of women, with red-green deficiency being the most common form. This test presents a series of plates and scores how many you identify correctly. While not a clinical diagnosis, it provides a reliable screening that can flag whether further evaluation by an eye care professional is worthwhile.
How to Use the Color Blindness Test
Click start to view the first plate. Each plate shows a pattern of colored dots with a number embedded in them. Type or select the number you see. If you cannot make out any number, choose the "No number" option. Work through all plates at a comfortable pace — there is no time limit. After the final plate, the tool displays your score and indicates whether your results suggest normal color vision or a possible deficiency. For the most accurate results, set your monitor to its default color profile, avoid using blue light filters or night mode, and ensure your screen brightness is at a comfortable level with no glare.
Why Color Vision Awareness Matters for Gamers
Many games rely heavily on color to convey critical information. Enemy nameplates, team indicators, minimap markers, and loot rarity tiers are often distinguished by color alone. Players with undiagnosed color vision deficiency may struggle to tell friend from foe or miss important visual cues without understanding why. Knowing your specific type of deficiency — protanopia, deuteranopia, or tritanopia — lets you enable the correct color blind mode in your games, which remaps problem colors to ones you can distinguish. Most modern titles include these accessibility options, but they only help if you know which setting matches your vision. A quick screening test is the first step.

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.
