About Color Guess

Color Guess is inspired by the training games web designers and front-end developers have long used to sharpen their sense of RGB and hex values. Newton laid the groundwork of modern color theory in 1672, and understanding how red, green, and blue mix into every screen color is now a basic skill for anyone building for the web.

The game shows you an RGB string and asks you to pick the matching swatch from a grid of colors. Three difficulty levels control how many choices you see and how close the decoy colors are. Play endlessly to build a streak or take the 60-second timer challenge for a quick skill check.

How to Play

Controls: Read the RGB value at the top of the board, then click or tap the swatch in the grid that matches it. Choose your difficulty and mode from the buttons above the board.

Objective: Pick the correct color for each RGB value. Build the longest possible streak in endless mode, or score as many correct answers as you can in 60 seconds in timer mode.

Tips & Strategy

• Identify the dominant channel first. If red is much higher than green and blue, you are looking for a warm, reddish swatch.
• Low numbers across all three channels mean dark colors; high numbers mean light ones. Use that to filter the grid quickly.
• If two channels are equal and the third is low, you are looking at a cyan, magenta, or yellow family color.
• In hard mode the decoys are very close to the answer. Compare swatches in pairs rather than scanning all at once.
• Play regularly. Recognizing RGB values is a learned skill, and even a few minutes a day noticeably improves your eye.
