Some random thoughts ....
How about an appropriately colored gel filter from a camera store or photographic supplier? Kodak used to make and sell this, but ....
Maybe the supplier of the photosensitive media can suggest a vendor for a bulb or a filter.
In a pinch, you may be able to get some candy-apple model spray paint at a well-stocked hobby store, and either spray a lampshade or the bulb itself.
