RGB vs CMYK
Differences, use cases, and when to use each
RGB is additive color for screens (R+G+B = white). CMYK is subtractive color for print (C+M+Y+K = black). They represent different physical color processes and have different gamuts — some colors exist in one but not the other.

| Gamut | Wider for screens | Narrower for print |
When to Use Each
When to Use RGB

When to Use CMYK
Use CMYK for print design: business cards, brochures, packaging, and any material produced by commercial printing where ink on paper creates color.
