Color Palette Generator
Build deterministic palettes from a base HEX color.
Generated palette
#1F6B45 · #6B1F45
How the color palette generator works
Generate complementary, analogous, triadic, split-complementary, and monochromatic palettes.
A complementary palette places the companion hue 180 degrees from the base hue.
Assumptions and limitations
Color harmony is a starting point; check contrast separately before using palette colors for text.
Inputs and results stay in your browser. Blank, invalid, or mathematically undefined inputs show a clean placeholder instead of a broken number.
Practical use
Use this design tool to explore scenarios quickly, then verify important decisions against the original source data or requirements.
Frequently asked questions
Does the color palette generator send my data anywhere?
No. It runs client-side in your browser and makes no network requests.
Why is the result blank or shown as a dash?
One or more inputs are blank, outside the accepted range, or would make the calculation undefined. Check the labels and enter finite values.
Can I use decimal values?
Yes, where decimals are meaningful. Counts that represent whole items may require integers.
