Color Glyphs - Introduction
Each glyph can have its own color information assigned to it. If a host application does not support the color font extension, the regular outlines will be shown. There are a couple of similarities with making a composite glyph, but there are also several differences.
Create a single color glyph
The easiest way to create a color version of a glyph is to select the "Colorize" option from the right-click menu when editing a glyph. This will automatically add the current glyph and assign a single color to it.
Create a multi-color glyph
To make a multi-color glyph, you need to add other glyphs and then define a color for each of these color members. Unlike composite glyph members, you can’t change the size or position of these color members. You will need to make sure the individual glyphs are all designed to fit into the color glyph. One other important requirement is the fact that the metrics of the base glyph and the color members must be the same. So the offsets (usually set to 0) and the advance widths have to match.
Switching between color and normal mode
When editing a glyph, click the "Color Mode" button or select Color Mode from the View menu.
