how to make colormap under fof not appear

[Grigri]

I am making a level pack and in one of the levels it has waterfalls, since i want fancy sloped waterfalls i use sloped fof's but when i add a color map it adds a giant noticable part of the color map under the sector, wich looks ugly. is there a way to fix this? or do i have to remove the colormap?

Apply the colormap to the FOF's control sector instead of the target sector.
