Photographic film is not light sensitive to red light ...
2nd Answer:
Actually, that is not true. When you are working with photographic film, any light at ALL will 'fog' the film and ruin your photos.
Photo paper is nowhere near as sensitive to red light as film is, so you can use a red "safe" light so you can see what you're doing as you print, develop, stop, and fix your photo prints. The room lights may be on as you rinse the print.
For a typical sunset you should use: Dark Purple Light Red Yellow Ochre Make sure that the purple and red are on top and below of each other and have the mixing where they meet.
"As i went outside to take out the trash, everything was dark."

Dark

You would use dark red
Yellow, blue and red.
Dark rooms are usually made for older cameras in order to develop previous taken films. It is easier to use Digital Cameras mainly because of it's versatility & ease.
If you use pure red, green and yellow paint, it will make black. If you use pure red, green and yellow light it will make white. If you use a tint of red, yellow or green, it will make either dark orange, dark purple, or dark green, or a mixture of the three.

red and black if you don't have red use pink, black and a little dark purple welcome What proportion of red to black and dark purple? thanks for help
Photographers use this red light called a safelight because the paper onto which the photograph gets exposed is not sensitive to the frequencies emitted by the 'red' light bulb. This is for black and white photography. Keep in mind, that although the bulb seems red, it has other filters, as opposed to a christmas red light, or a red LED. These filters, usually block frequencies under (estimate) 590-650nm (nanometer). So anything above those frequencies the paper doesn't see, but we can, up until it becomes invisible light to us (350-700 nm is more or less what we see).
Just make sure that you do not use cheap filters. Always use filters as good as OEM filters at least. Don't use FRAM.
