Thehsl()option in CSS also makes it easy to adjust the tone of a color. Mixing white with a pure hue creates a tint of that color, and adding black will make a shade. Alternatively, a tone is produced by adding gray or by both tinting and shading. Recall that the 's' and 'l' ofhsl()stand for saturation and lightness, respectively. The saturation percent changes the amount of gray and the lightness percent determines how much white or black is in the color. This is useful when you have a base hue you like, but need different variations of it.
All elements have a defaultbackground-coloroftransparent. Ournavelement currently appears to have acyanbackground, because the element behind it has abackground-colorset tocyan. Add abackground-colorto thenavelement so it uses the samecyanhue, but has80%saturation and25%lightness values to change its tone and shade.
