Visualize warm/cool color temperature and generate palettes. Color Temperature Tool is a free online tool from the ToolsRift Color Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Enter a color to see its warm or cool classification, then generate a palette across the temperature range.
Warm colors sit in the red-orange-yellow range and cool colors in the blue-green-violet range of the color wheel.
The tool analyzes the hue to place your color on a warm-to-cool scale and can build matching palettes.
It is inspired by it — lower Kelvin light is warm (orange) and higher Kelvin is cool (blue), which mirrors the hue scale.
