The colors are not created by the bulb. Instead, some form of filter (film, slides, transparent writing surfaces, etc) is placed between the bulb and the screen (or whatever surface onto which the light is being projected). The filter blocks certain portions of light from passing through, and allows others. The result is that a lighted version of the filter's coloration pattern (picture, writing, etc) is visible on the screen or surface.
