Vector Color Management: From RGB to CMYK to Pantone

Understanding Color in Vector Graphics

Color management is often overlooked in vector graphics, but it's critical for ensuring your designs look consistent across screens, printers, and materials. This guide covers everything you need to know.

Color Space Fundamentals

RGB (Red, Green, Blue)

Digital display standard:

RGB Color Space:
Additive color model
Values: 0-255 per channel
16.7 million possible colors
Used for: Screens, web, digital

When to use RGB:

CMYK (Cyan, Magenta, Yellow, Key/Black)

Print production standard:

CMYK Color Space:
Subtractive color model
Values: 0-100% per channel
Smaller gamut than RGB
Used for: Print production

When to use CMYK:

Pantone (Spot Colors)

Brand-critical colors:

Pantone System:
Standardized color matching
Physical swatch references
Consistent across printers
Premium/specialty options

When to use Pantone:

Color Conversion Challenges

RGB to CMYK Issues

Common problems:

RGB Colors Outside CMYK Gamut:
Bright blues → duller in print
Neon greens → significantly muted
Vibrant purples → shift in print
Pure RGB colors → unprintable

Solutions for Gamut Issues

Setting Up Color Profiles

ICC Profiles

Color management standards:

Common Profiles:
RGB: sRGB, Adobe RGB, Display P3
CMYK: US Web Coated (SWOP), Fogra39

Software Configuration

Adobe Illustrator settings:

Edit → Color Settings:
Working RGB: sRGB
Working CMYK: US Web Coated v2
Color Management Policies: Preserve
