How does HEX/RGB conversion work?

Enter either HEX or RGB and the other updates automatically. HEX is common for web; RGB for design tools.

Can I copy the recommended colors?

Yes. Copy the HEX or RGB value shown next to each recommendation. Use the copy button if available.

What is a HEX color code?

A HEX code represents a color as a 6-digit hexadecimal number (e.g. #FF5733). The first two digits are red (R), the middle two are green (G), and the last two are blue (B). HEX is widely used in CSS, HTML, and design tools.

What color harmony modes are available?

The tool provides Complementary, Analogous, Triadic, Split-Complementary, and Monochromatic harmonies. Each mode generates a palette of colors that work well together according to color theory.

Should I use RGB or HEX?

Both represent the same colors. Use HEX for CSS and HTML. Use RGB in design tools like Figma, Photoshop, or Illustrator. You can convert between them freely — both formats are supported here.
