The color filter is usually installed in front of the light source, so that the human eye can receive the saturated light of a certain color. There are infrared filters, green, blue, etc. Compared with UV filters and VD filters, it is a general term for colored filters. Such as contrast filter, color separation filter, LB filter, etc.
