ColorPairLabWhite hex and RGB values
The CSS keyword white gives you #FFFFFF, or rgb(255, 255, 255).
White works as a clean page or card background. Set it explicitly when you need an exact match; a transparent card will take on the colors behind it.
Compare black and white text
| Text / background | Ratio | AA normal | AA large | AAA normal | AAA large |
|---|---|---|---|---|---|
| #000000 / #FFFFFF | 21.00:1 | Pass | Pass | Pass | Pass |
| #FFFFFF / #FFFFFF | 1.00:1 | Fail | Fail | Fail | Fail |
Black text has the higher contrast on white: 21.00:1. The table compares both options against all four text thresholds, using the unrounded values for pass or fail.
Try white in a layout
The CSS sample below uses black text on #FFFFFF. Preview a 16 px label and a 24 px heading to compare normal and large text. Swap the colors to try white as the text color; the ratio stays the same.
.sample {
background: #FFFFFF;
color: #000000;
}Copy the exact color
Use the converter to copy HEX, RGB or HSL. If you edit in HSL, the final value is rounded to eight-bit sRGB so the preview and exported color agree. For text over an image, gradient or translucent layer, check the finished design separately.
