FAQ
Named CSS colors vs HEX?
Named colors (rebeccapurple) are convenient in notebooks. HEX and tuples are explicit for publications and brand guidelines.
RGBA tuples for transparency?
Use a fourth value in (r, g, b, a) with a between 0 and 1 for overlays and confidence bands.
Can I copy the syntax chips?
Yes — click the secondary chip to copy platform syntax. HEX and RGB chips copy sRGB values for mockups, design handoff, and ChromaXP tools.
Are RGB and CMYK print-ready?
RGB and CMYK here are computed from HEX for quick reference. For ink and paper, re-check against your print profile or Pantone bridge.
