Paletton FAQ
Is Paletton free to use?
Yes. Paletton is completely free with no account or sign-up required. The site is ad-supported with an optional donation option.
What color schemes can Paletton generate?
Paletton generates monochromatic (single hue), complementary (opposite hues), triadic (three evenly spaced hues), tetradic (four hues), and free-style palettes. Each hue includes five shade variations.
Does Paletton check for color accessibility?
Yes. Paletton includes a WCAG contrast ratio checker that tests all color pairs against accessibility standards, plus a color blindness simulator showing how palettes appear to people with various types of color vision deficiency.
What formats can I export my palette in?
Paletton exports to HTML, CSS, LESS, XML, PNG images, Adobe Photoshop ACO swatch files, and GIMP GPL palette files, covering most design and development workflows.
Why does Paletton use RYB instead of RGB?
Paletton uses the classical RYB (Red-Yellow-Blue) color wheel from traditional art and color theory, which produces more visually harmonious palettes for design purposes than the additive RGB model used for screen displays.
