init_color

Changes the definition of a color. It takes four arguments:

• the number of the color to be changed, color

• the amount of red, r

• the amount of green, g

• the amount of blue, b

The value of the first argument must be between 0 and COLORS. (See the section Colors for the default color index.) Each of the last three arguments must be a value between 0 and 1000. When ::init_color is used, all occurrences of that color on the screen immediately change to the new definition.
