RGB Rush

RGB Rush gives you a random colour to recreate using sliders or by entering its values. Your accuracy determines your score, and you can track your colour skills with graphs showing strengths and weaknesses for individual channels.

Colour spaces

You can practise assembling colours from their component values in five colour spaces:

• CMYK: work with cyan, magenta, yellow and key, the components used in printing.
• HSV: work with colour, intensity and brightness.
• RGB: work with red, green and blue, the colours emitted by your pixels.
• HEX single: practise understanding base 16.
• HEX: use the same components as RGB, but with letters as well as numbers.

Game modes

• Practice: work at your own pace and get familiar with how the colours work.
• Blindfolded: you cannot see your colour until you submit it.
• Timed: race against the clock; only guesses with at least 90% accuracy reset the timer.

Tracking accuracy

Higher accuracy gives you a better score. The reports show your strengths and weaknesses by individual colour channel, such as whether you are better at distinguishing blues or whether your monitor has low contrast in green. The game can also be used for prototyping, website design, photo editing and digital art, or to demonstrate your colour skills at an interview.
