Logo Colors

Logo color names are the same as the standard Web color names. These color names go back a long way to the first graphic subsystems based on the X11 architecture in 1986. Nowadays, every Web browser understands these color names.

The tables below display the color names along with their color index and the RGB values, which are the intensities of the Red, Green and Blue components of a color, expressed as values between 0 and 255.

All Logo commands that take a color as input accept either the color name, the color index (which must be between 0 and 13), or a three-element list for the three RGB color values. A fourth list element describes the alpha value, which is a value between 0 and 1. The lower the alpha value is, the more transparent the color is. A value of 1 makes a color fully opaque, and an alpha value of 0 makes it invisible.

Color indexes and color names do not have an own alpha value. Instead, their alpha value is set to 1 (fully opaque), unless you use a turtle command. In that case, the turtle’s alpha value (which you set with the SETALPHA command) is returned as the alpha value of a color name or color index. If you use a color name to work with the background, a value of 1 (fully opaque) is used. The same happens if you supply a list of three color values without an alpha value; for commands related to a turtle, the turtle’s alpha value is used; for all other purposes, an alpha value of 1 is used. See the SETALPHA command for a few examples.

The following commands all set the pen color to Gold:

If you want to use a gold color with transparency, you can use a four-element list as in this example:

The special color "TRANSPARENT (which is [0 0 0 0]) clear any color.
