The colorize effect removes color information from underlying visuals and applies a flat color
to the resultant grayscale map. For instance, setting the
forecolor attribute to
a light yellow color will produce a simple 'sepia' effect.
This module also supports the
backcolor attribute, and
fade can be
used to blend between the two different colors over time.
