Odd color practice
Odd Color Out is simple: look at nine color tiles, find the one that is slightly different, and finish ten rounds.
Core rule
Each round shows a 3x3 grid. Eight tiles use the same base color, and one tile is shifted a little in hue, saturation, or brightness. Tap the tile that does not belong.
Difficulty
The first rounds use a clearer shift, then the game reduces the gap. Later tiles can look almost identical, so the answer may hide in the pattern.
How to look
Sweep across the rows, then compare any suspicious tile with its neighbors. A quick whole-grid scan usually works better than staring at one square.
Result
After ten rounds, the result card shows your correct answers, accuracy, best streak, and a compact round summary. You can share the card as a PNG.
The goal of Odd Color Out is to find the one tile in a 3x3 grid that is slightly different from the other eight tiles. You play ten rounds, then receive a result card with your correct answers and accuracy.
No. Odd Color Out focuses on careful visual comparison rather than a countdown. You can take a moment to scan the grid, compare nearby tiles, and tap only when you feel confident.
Odd Color Out gradually uses smaller differences between the base color and the odd color. Later rounds may change only brightness, saturation, or hue by a small amount, so the odd tile blends in more effectively.
