Best text color

Only one of black and white can be right. This is the one, with the number that proves it.

Make it accessible

A contrast checker tells you that you failed. This tells you what to ship instead — same hue, same saturation, lightness moved only as far as WCAG demands.

Accessibility — WCAG contrast

Contrast is symmetric, so each row covers both directions: #02babc as text on that neutral, and that neutral as text on #02babc.

Roughly one man in twelve has some form of colour vision deficiency. If any of the three panels above is hard to tell apart from a neighbouring colour in your palette, add a shape, an icon or a label so the meaning does not rest on hue alone.

Color scale — 50 to 950

A Tailwind-shaped ramp built around this exact hex. #02babc is pinned to step 700; the rest hold its hue and let saturation ease off at the extremes so the pale end never turns neon.
