Chromata is FREE android application designed to help people determine if they have slight form of color blindness.

About
The app simulates the so called 'Farnsworth–Munsell 100 hue test' and it is designed to tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues.

How it works
The app displays series of images composed of circles with varying lightness and size. Then you have to look up for numbers, letters or symbols that are embedded within the circles pattern and click the button corresponding to the shape you see.

Hint
Should you guess? The answer is yes! Even if you are not 100% certain about the shape you see it is better to take your best guess. When you are completely unsure then simply click the button 'Unsure' and when you see nothing simply click the button 'Nothing'.

Result
Test results may vary depending on the screen quality of your device and this will lead to different results on different devices. When you do the test make sure you set the brightness to 100%, and you have turn off the 'Eye comfort' modes if your device supports it.
