CSS Reference Guide: color
Blog post from LogRocket
The CSS color property is used to set the foreground color of a text element or its decorations, offering various methods for specifying colors, including keywords, named values, hex values, RGB/RGBA values, and HSL/HSLA values. Keywords like "currentcolor" inherit the color value, while "transparent" denotes full transparency. Named values are predefined colors such as red or green, each with corresponding hex values, which are alphanumeric strings representing RGB components. Hex values can be six or three characters long, while RGB values are specified with three numbers ranging from 0 to 255, or as percentages, with RGBA adding an opacity level. HSL values define colors based on hue, saturation, and lightness, with HSLA also including opacity.
