Built-in colors

Author has four built in colors: black, red, green, and blue.

Custom colors

Author can accept any HTML/CSS compatible color and color type (HEX, RGB, etc) as long as the color is entered in a web compatible format.

Custom inspector

Author has a color inspector built in. One click of the button and all active colors are shown. This is really useful for when you come back to a document and forget what color you had used.
