There are colored safelight bulbs, I have a couple.
You also don't have many options on size. One of mine is small similar to a PH-140 enlarging bulb, the 2nd is HUGE like a G40 globe bulb.
I see that Adorama has similar bulbs, and they are expensive, the small size is $17

Given the bulb situation, I would just keep the stained glass out of the darkroom.
