Its supposed to match your flash to tungsten light, its geared to make a daylight source closer to 3200, but i find the canon 580exII is warmer than daylight and it doesnt quite match 3200 on that flash. Its more like 4000-4400 (depending on how warm you like your image) to get reasonably accurate white balance from the flash. It can give a nice effect when trying match ambiant light.

If you want to "warm" an image up. Tungsten light like others have mentioned. I prefer gels, bit more accurate with 1/4, 1/2 and full cuts so you can pick and choose (CTO that is for warming). If you don't mind abusing your gels a little bit you can jam them under a standard Sto Fen diffuser and BOOM you have a gelled diffuser~
