Choosing a primary brand color: five criteria
A startup primary brand color should meet five criteria simultaneously. (1) Distinctive within the category: visually differentiated from the most common colors used by direct competitors. (2) Appropriate to the product: the color should be semantically congruent with what the product does and who it serves — a security product in vivid pink may be memorable but will work against trust building. (3) Scalable to a design system: the color should have enough tonal range to produce a complete design system (light backgrounds, medium UI tones, dark text-safe versions) without becoming muddy or losing identity. (4) Accessible at sufficient contrast: the primary color should achieve 4.5:1 contrast with a white or near-white background for text use, or at minimum 3:1 for large text and UI components. (5) Reproducible across media: the color should be specifiable in hex for screen, as close a CMYK match as possible for print, and as a Pantone match for premium print and merchandise.
