To remove black light paint, start by using a mixture of warm water and mild soap to gently scrub the area with a soft cloth or sponge. For stubborn stains, you can apply a mixture of vinegar and water or use isopropyl alcohol. If the paint is still not coming off, consider using a commercial paint remover, following the manufacturer's instructions carefully. Always test any solution on a small, inconspicuous area first to avoid damage to the surface.
No. The stars would still provide light, although a great deal less than the Moon. In many urban and industrial areas, the "light pollution" from homes, industries, and street lights provide a lot of reflected artificial light.
Bleach shows black under a black light or rather it cancels white papers glo effect where bleach is still present
No
Colour is the human perception of certain frequencies of light. Without light, there is no colour to be perceived. A dark room may still have light in it (and in fact it does in the form of infrared light), but the intensity of that light is small, and the human eye may not be able to see it.In short, no light = no colour.
Typically, you would want to lay down the lightest colors on the canvas and then paint over the light colors with a darker color. It looks better because if you did it the opposite direction, the darker colors would still show through the lighter colors to a degree.
Yes but shes still black
Well, If it is called "Mirror Paint" I'm pretty sure that you can put it on there, if normal paint then i would recommend painting the frame instead of the mirror there is Glass Paint which i recommend you use instead.

Yes
Light does have mass - since it has energy, it follows that it also has mass. Its REST MASS or INVARIANT MASS, however, is zero. On the other hand, the black hole distorts space and time in its surroundings so much that the only paths a ray of light (or anything moving at the speed of light or less) can take, will take it deeper into the black hole.
