Umber in HSL is hsl(21, 16%, 33%). HSL stands for Hue (21 degrees on the color wheel), Saturation (16% color intensity), and Lightness (33% brightness).

This makes Umber a dark, muted warm-toned color.

When designing for print in Adobe InDesign or Illustrator, use these exact CMYK values to ensure accurate color reproduction. Screen colors (RGB) often appear more vibrant than their printed CMYK equivalents, so always request a physical proof for brand-critical materials.

What colors pair well with Umber in design projects?

Brown pairs naturally with cream, tan, orange, and forest green for warm, earthy palettes. It works well in food, nature, and vintage design contexts where warmth is desired.

Is Umber (#635147) accessible for web design and WCAG compliant?

Medium browns often fail contrast requirements on white. Dark browns (#3E2723 and darker) work as text colors, while lighter browns should be reserved for backgrounds with dark text. For Umber specifically: as a dark shade (lightness: 33%), it can work as a text color on light backgrounds, but verify the exact contrast ratio using a contrast checker tool. WCAG 2.1 requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (18px+ bold or 24px+ regular).
