Colordef can be used to define a new color named color_name or to change the definition of an existing color. While both color_name and existing_color_name can contain letters, digits, and underscores, only existing_color_name can contain spaces. The red, green, blue, and alpha arguments must be floating point numbers between zero and one, inclusive. The alpha value denotes transparency, where 0.0 means completely transparent (invisible) and 1.0 means completely opaque (the default).
