====== Colors ======

LCD4Linux supports graphic displays with colors, although there are only few (very vew :-) displays that are capable of displaying colors. At the moment only the X11, Image and 4D Systems drivers use color support.

A color specification has the format RRGGBBAA, representing 32 bits of Red, Green, Blue and Alpha (8 bits each).

You may omit the Alpha component, resulting in RRGGBB, which uses a alpha value of FF (255, completely opaque).

Every widget can use it's own color, and there may be a 'generic' foreground and background color (specified in the //Driver// section) which will be used if the widget color is missing.

Some drivers (namely the X11 and the Image driver) allow you to specify a //base color//, which is the color of the (imaginary) backlight. With this in mind, you can use alpha-blending to get foreground and background colors automagically.

<code>
basecolor  00AA00   (green)
foreground 000000cc (black, nearly opaque)
background 00000033 (black, nearly transparent)
</code>


will give you a green background, with slightly green pixels. To switch to red backlight color, just change the base color, and you're done.
