Accessibility Notes

  • 1

    Pure black (#000000) on white achieves 21:1 contrast — the highest possible value under WCAG.

  • 2

    Pure black can cause visual discomfort (halation) in bright environments for some readers; #1A1A1A or #111827 are softer alternatives that still pass AAA.

  • 3

    Black text on dark backgrounds has near-zero contrast — always verify black text is only used on light surfaces.

  • 4

    Black is fully accessible for all types of color vision deficiency; hue is irrelevant when one color is black.

  • 5

    For printed material, 100% K black should be used carefully — rich black (CMYK blend) may look different across monitors.

Design Tips

  • Prefer #1A1A1A or #111111 over pure #000000 for body text — softer black reduces eye strain on bright screens.

  • Black on white (21:1) is WCAG AAA. Black on off-white (#F8F8F8) is 18.1:1 — still AAA.

  • Dark mode: use near-white (#F1F5F9) text on near-black (#0F172A) background — same AAA outcome, less harsh.
