FAQ
FromArgb with or without alpha?
Color.FromArgb(255, r, g, b) sets opaque alpha in the first argument. Omitting alpha uses 255 by default in some overloads — check your .NET version docs.
KnownColor vs custom RGB?
Color.MediumPurple is fast for prototypes. Brand UI should use explicit RGB/HEX from your design system.
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.
