Color

A Color value can be defined in any of the following ways:

• Hexadecimal: #hex, e.g. #4290F5 (case-insensitive);
• RGB: rgb(red 0-255, green 0-255, blue 0-255), e.g. rgb(66, 144, 245);
• RGBA: rgba(red 0-255, green 0-255, blue 0-255), e.g. rgb(66, 144, 245, 0.8);
• HSV: hsv(hue, saturation 0-100, value 0-100), e.g. hsv(214, 73, 96);
• HSL: hsl(hue, saturation 0-100, lightness 0-100), e.g. hsv(214, 90, 61);
• Named: a CSS3 color name, case-insensitive, without dashes (e.g. blue, darkorange).

Except for named ones, any color in a code span (i.e. wrapped by backticks) automatically previews its content in a small box next to it.
