What Light will not mess up photography paper when used in a darkroom?

In a darkroom, the light that will not mess up Photography paper is typically red or amber light. These colors are safe for black-and-white photographic paper because they do not affect the light-sensitive chemicals in the paper. Photographers use special safelights that emit these wavelengths to allow them to work without exposing the paper to unwanted light. However, it's important to ensure that the intensity and duration of exposure to safelight are kept within recommended limits to avoid fogging the paper.
