Guess mode: read the colour swatch up top and tap the matching #hex code from the four options. A correct pick extends your streak; a miss resets it but reveals the right answer so you learn the channels. Get a wrong one very close and the game tells you how near you were.

Match mode: a target colour appears with its hex label. Drag the R, G, B sliders until your preview matches, then submit. Score each of five rounds on how close you get, then it tallies your average.

In Guess mode, tap an option, or on desktop press 1–4 to pick the options in order. In Match mode, drag the R, G, B sliders, then tap Submit guess. After Match's five rounds, press Enter or Space to play again. Switch modes any time with the Guess / Match toggle.

• Read the channels: high R with low G and B reads warm red; high G alone reads vivid green.
• Guess mode saves your longest streak; pass it mid-run for a live "New best!" Streaks of 3, 5, 10 and up get a celebration.
• In Match mode, 85+ per round is strong and 100 is a perfect colour match.
• Your Match best is the highest five-round average you have hit.
