3.4.4 Colors

Many element properties represent colors. In HTML, colors may be represented by an RGB string, which contains 7 characters. The first character is #, the rest are hexadecimal digits (0-9 and a-f or A-F); the first two digits are for the red component of the color, the middle two for the green component, and the last two for the blue component. For example, "#FFFFFF" is white, "#000000" is black, and "#00FF00" is green.

There are also predefined color names. The -native methods use these names in strings, while their nonnative counterpart methods use the names as symbols.

The predefined color names are:
