How to play

Try to guess the hexadecimal color code that matches the color of the red square.

• A blue background means your guess in that component was too high.
• A yellow background means your guess in that component was too low.
• A green background means your guess was correct.

Note that feedback is for each primary color component, and not the individual digits. If you guess 2 0 and get yellow, it means that "20" is too low, not that "2" and "0" are individually too low (i.e., the correct guess could be 2 1).
