What are Web-Safe Colors Anyway?
Web safe colors reside in a series of color schemes arranged in a "cube" of colors that relate and have a Hexadecimal corresponding value. This value can be decoded by the browser and displayed on the screen. For example: This text has a color of #FFFF33. This text has a color of #993399. Other colors are just based on this 6 digit hexadecimal color number. Even the color black used in this color text has a corresponding number of #000000.
