Color of any thing in a 100% dark room would be black. Since, the red rose appears red because when light falls on it, it absorbs all other components of light except the red one. It reflects the red light and hence we perceive it as a red rose.
Moreover, 100% dark room does not exist, practically .
Hope this helps.

Does the rose exist in a 100% dark room?

Color is a perception requiring sight and fully functioning cones at the back of the eyeball. Color is not just a matter of some physical characteristics of the objects. For example, a fully color blind person would see that rose as shades of gray, white, and black. It would be colorless to that person.
Most, if not all, darkrooms use red light when processing the film. This provides sufficient light to see what the developer is doing and, yet, it will not expose the film. Under red light conditions, objects, like the rose, that would be seen as red under white light appear very light...almost white with a hint of pink.
Of course if by "100% dark room" you meant totally black and devoid of light, some of the previous answers are correct...you'd "see" nothing but black, including the rose.

i think your eyes see the color through reflected light
so if the room is 100% dark the rose will stay red but your eyes wont be able to see it do to having no light in that room

If the room is 100% dark, its mean that the room are no light and so dark. The rose(s) will be invisible and cannot be seen. So there will be no color at all.

SInce colour depends on Light to be visible, then the red or not so red rose will obviously be same colour as the room.

It is still red, you just can't see it. The physical structure of the epithelium of the rose is designed to reflect red light. While there is no light to reflect, it nonetheless has the ability to do so and is thus still red.

Poppa beat me to it. The answer to your question lies in defining what you mean by color. The rose still has the same physical properties. The absence of light does not change that (as far as we can prove :P ).

A 100% dark room does not exist. Read your thermodynamics and quantum mechanics books.
I love physics. It takes all the wind out of any nonsense philosophers have ever come up with.
