d3.color()

d3.color(specifier)

Parses the specified CSS Color Module Level 3 specifier string, returning an RGB or HSL color. If the specifier was not valid, null is returned. Some examples:

• rgb(255, 255, 255)
• rgb(10%, 20%, 30%)
• rgba(255, 255, 255, 0.4)
• rgba(10%, 20%, 30%, 0.4)
• hsl(120, 50%, 20%)
• hsla(120, 50%, 20%, 0.4)
• #ffeeaa
• #fea
• steelblue

The list of supported named colors is specified by CSS.

Note: this function may also be used with instanceof to test if an object is a color instance. The same is true of color subclasses, allowing you to test whether a color is in a particular color space.
