Frequently asked questions
How many colors does the generator produce?
The generator produces a primary palette of 5-6 colors plus tints and shades of the base color, giving you a comprehensive system to work with.
What color harmony types are generated?
Complementary, analogous, triadic, and split-complementary palettes are all generated from your base color.
Can I export the palette?
Copy individual HEX codes or export the full palette as CSS variables for direct use in your stylesheet.
How do I choose a good base color?
Start with your primary brand color or the dominant color you want to build from. The generator creates supporting colors that work harmoniously with your choice.
Does it work offline?
Yes.
What is the difference between a tint and a shade?
A tint is the color mixed with white, making it lighter. A shade is the color mixed with black, making it darker. Both are created by adjusting the lightness value in HSL while keeping hue and saturation constant.
