Each colour is represented by three numbers, each ranging from 0 to 255. The first number represents how much red there is, the next represents how much green there is and the third number represents how much blue there is. The higher the number, the more of that colour. So, for example (255, 0, 0) represents a full red colour, because the number representing red is the highest possible value (255) and there is zero green and zero blue. (0, 0, 0) produces black and (255, 255, 255) produces white. These three colours can be combined to produce any visible colour. This way of representing a colour by three numbers is known as the RGB system.

This app challenges you to guess the red, green and blue (RGB) components in a randomly selected colour! Difficult? Yes, it is indeed difficult and challenging, but playing it will be great fun!!

Playing the game will also be a great learning experience because it trains your eyes to see the amount of red, blue and green colours present in a given colour. This gives a better understanding of the composition of colours and helps you in choosing the appropriate colours in the design of a user interface.
