Hexadecimal Colors (Colours)
Hex colors are key to creating / designing page layout using CSS. They are used to define all of the colors on a page.
When using the numerical colors, don't forget to prefix them with # i.e. #ff0000 is red, #00ff00 is green & #0000ff is blue.
These are the 140 colors which can be safely used in name form. They should be recognised by all browsers i.e. color:red.
These colors are the 216 colors which should render safely in all browsers and media types. They have been adopted by (amongst others) Windows, Linux & MAC. Note that all of the codes present a double-up for R G & B i.e. color BLUE is represented as #0000ff which equals RED=00 GREEN=00 BLUE=ff.
