Conversion light filters are designed to correct the color temperature of light sources such as external lighting, museum lighting, etc.
The "blue" series conversion filters increase the color temperature of incandescent lamps. The most popular is the Day Light Filter 80A. It converts the spectrum of a halogen lamp into a midday ambient light spectrum.
"Orange" series conversion filters lower the color temperature of light sources.
