How can I effectively pair #00b9dd in a UI design?
#00b9dd functions best when balanced against neutral, grounded tones like charcoal or deep navy. By using it solely for interactive elements such as buttons or links, you ensure the color remains a sharp, attention-grabbing highlight without overwhelming the overall layout.
Is #00b9dd suitable for text on a white background?
While #00b9dd is highly readable, it does not meet standard WCAG accessibility requirements for body text against a white background. It is better reserved for UI accents, icons, or decorative elements where high legibility is not the primary requirement for user retention.
Is #00b9dd readable on white or black?
#00b9dd has a 2.33:1 contrast ratio on white and 8.98:1 on black. WCAG asks for 4.5:1 for body text and 3:1 for large text, so on white it is too faint for text and on black it works for body text. Try other pairs in the contrast checker.
