Frequently Asked Questions
- Why do the colors look balanced?
- They are spaced evenly around the hue wheel (e.g. every 72° for 5 colors). This keeps the palette cohesive while still distinct.
- Can I get a single random color?
- Yes — set the count to 1 for a single random color with its hex and RGB values.
- Random or curated?
- Harmony-mode random — palettes follow color theory, not noise. Lock favorites and reroll the rest.
- Export formats?
- HEX, RGB, and HSL copy with one click for CSS, tokens, and print specs.
- Brand-safe?
- Starting points, not finished identities. Refine winners with contrast checks and print proofs.
- Stored anywhere?
- No. Generation runs locally in your browser. No palettes are stored.
