Brand colors are the specific hues a company uses consistently across its logo, website, packaging, and marketing materials. They form a core part of visual brand identity and help consumers instantly recognize the brand—like Coca-Cola red or Starbucks green.
Knowing exact brand colors helps designers create complementary materials, maintain brand consistency in collaborations, and build color palettes that harmonize with established brand identities. Accurate color codes prevent costly mismatches in print and digital media.
HEX is the standard for web design (CSS). RGB is used in digital screens and graphic software. HSL (Hue, Saturation, Lightness) is more intuitive for adjusting colors—designers often prefer it for creating variations like lighter tints or darker shades.
Color values themselves are not copyrightable, but using brand colors to imitate or misrepresent a trademarked brand may raise legal concerns. Always use brand colors respectfully—for reference, inspiration, or legitimate design work rather than deception.
We source color values from official brand guidelines, press kits, and reputable design references. However, brands occasionally update their palettes. We recommend verifying against the official brand style guide for critical commercial projects.
Study the relationships between a brand's primary and secondary colors. Notice how complementary or analogous hues work together. Use tools like color wheels to adapt these relationships to your own unique palette—take inspiration from the harmony, not the exact values.
Primary colors are the main identifying hues (like Netflix red). Secondary colors support the primary palette in UI, illustrations, and marketing. Many brands also have accent colors for calls-to-action or highlights. This tool shows all official brand colors where available.
