Colour Blindness is a free Android game developed by dya that aims to help people test their color vision. This game is specifically designed for people who suffer from color blindness, which affects 1 in 12 men and 1 in 200 women worldwide. In the UK, this means that approximately 2.7 million people are color blind, with most of them being male.

The game consists of two main sections: Warm Up and Game. In the Warm Up section, players are familiarized with the different types of color blindness and how it affects the way they see colors. The Game section is where players can test their ability to identify colors. The game has a simple user interface, making it easy to use for people of all ages.
