To use this, save this file in a local folder, say as ~/local/compiz/reddish, and configure the color-filter to point to it using the CompizConfig program.

To activate the effect, you can use the keyboard shortcuts defined in the CompizConfig program.

The values in line #4 can be tweaked to get the right color effect. That line specifies the multiplication factor for Red, Green, Blue and Alpha. When the factor is one, that channel remains unchanged. When zero, it is completely filtered out.
