There are 6 filter colors commonly used in black and white photography - red, orange, yellow, green, purple, and blue. Each lets through its own color of light and blocks other colors to varying degrees. For example, a red filter will let red light through, but block most green and blue.
The result is that colors matching the filter color appear brighter in the final image, while other colors appear darker. In black and white photography this means that objects appear as lighter or darker shades of grey.
