Colour matching challenge
Match the target colour’s RGB values, with a numeric alternative to colour perception.
Your choices
Numbers shown initially are examples. Replace them with your own figures. Inputs are processed for this response and are not stored by this tool.
How it works
The target is #5144C3: red 81, green 68, blue 195. Score measures Euclidean distance in RGB, not perceptual similarity. The target values stay visible so the game is usable without distinguishing colours.
Example and practical tip
Try estimating the colour first, or use the target numbers to practice translating RGB channels into a hex colour.
