Previously, we converted colors to their RGB values immediately when they were set. This meant that their semantic meaning was lost, we could not tell a precise RGB value apart from a named/indexed color. The new way of storing colors will allow us to retain this information, so we can change a color scheme on the fly, and previously emitted text will also be affected.
