Usage rules

​
Yellow / orange family

Use for:
  • Eval Labs identity accents
  • status markers
  • gentle highlights
  • callout warmth

​
Black / ink

Use for:
  • body text
  • headings
  • icon strokes
  • serious source-truth language
Eval Labs should not rely on pale gray body text for important claims.

Cool Eval accent

Use for:
  • Eval Labs navigation and interaction accents
  • approved gradient logo variants
  • restrained product-specific emphasis
