About Aqua
Aqua (aqua) is a medium, vivid cyan with the hex code #00ffff, or rgb(0, 255, 255). In HSL it sits at a hue of 180°, 100% saturation and 50% lightness. CSS also accepts the spelling cyan for exactly the same color. It is one of the 148 named colors every browser understands, so you can write color: aqua; instead of the hex value.
Using Aqua for text and backgrounds
| Pairing | Contrast ratio | WCAG |
|---|---|---|
| Aqua text on white | 1.25 : 1 | fails |
| Aqua text on black | 16.75 : 1 | AAA |
On a aqua background, use black text (16.75 : 1). WCAG asks for at least 4.5 : 1 for body text and 3 : 1 for large text. Check other pairs with the Contrast Checker.
