These filters control the spectrum by reducing the transmission at specific wavelengths. They are primarily used to colour balance films, the required filter being determined as a result of tests, or as specified by the manufacturer. They can also be useful for correcting light sources for which no one conversion filter exists, or for adding a deliberate colour bias. ...

Some photographic situations require specific colour corrections. For example, when shooting daylight film under fluorescent lighting, some magenta correction is needed in order to remove the greenish tint that would otherwise appear. The amount of colour correction required is most accurately measured via a colour temperature meter. Colour Compensating filters are available in the three primary colours: Red, Green, & Blue; & in the three secondary colours: Cyan, Magenta, & Yellow. A typical designation for one of these filters is CC30M. The 'CC' stands for Colour Compensating. The '30' stands for a density of 0.30 & the 'M' is for magenta. Lee colour compensating filters are made in the following increasing densities: 0.025 (CC025), 0.05 (CC05), 0.10 (CC10), 0.15 (CC15), 0.20 (CC20), 0.25 (CC25), 0.30 (CC30), 0.40 (CC40), 0.50 (CC50). You can sandwich as many as three Lee polyester filters together without a noticeable loss of image quality. ...
