"""A color database for Leo.

leo_color_database is a dictionary of color names mapped onto the
colors '#rrggbb' representation.

The color names are derived from standard Linux color names which
includes all Tk color names.

The names have been normalized by excluding spaces and removing
capitalization. This should also be done for all new colors.

Accessor functions are provided which will normalize name requests
before looking them up in the database.

These are::
    
    getColor (aka: get)
    getColorRGB (aka: getRGB)
    getColorCairo (aka: getCairo)

Use these functions as follows::

    import leo.core.leoColor as leoColor    
    leoColor.getRGB(name, default)

If neither 'name' nor 'default' can be translated then accessor functions
will return None.
