About Black

Black is a very dark neutral gray with the hex code #000000. In RGB it is made of 0 red, 0 green and 0 blue; in HSL its hue is 0°, with 0% saturation and 0% lightness. Its perceptual lightness (OKLCH L) is 0.0%.

It is a CSS named color, so you can write "black" anywhere CSS accepts a color. Against white it has a contrast ratio of 21.00:1 and against black 1.00:1, so white text reads better on it and passes WCAG AA for normal text.
