If your mirror has a frame, just paint the frame to match the floor. Or if no frame, one could be built around it and then painted.
Does your mirror have a frame around it? If so, what is the frame made from? Chalk paint works well for a project like this. You can paint on wood or plastic with chalk paint. It willneed to be topcoated with a chalk paint wax or a water based poly to protect the chalk paint finish.
If you are trying to match a color go to Home Depot and get sample chips of color and bring them home to match. Otherwise just paint it a shade of grey you like.

Hi, do you have a picture of the mirror? Are you just looking to paint the frame in the same colour as the floor? If the mirror has a frame you can get a paint similar to the floor colour and paint it, if not, you would need to make one first. If you are having a hard time finding a colour to match the floor and can't find one close enough, you could use a complimentary colour. Just about any colour with go with a beautiful neutral like grey.
I would go with a bright white or a metallic paint for the frame. If you don't or can't take it down, just tape the area surrounding it and the face of the mirror. Then paint as you would any other trim.
Tape off mirror and paint. (Chalk paint, by the way, goes over anything!). You may have some issues with the reflection of the old color tho... so taking off the frame and painting the back too will be the best way to do it.
Do you mean paint just the frame?
If your floor has a design on it you could maybe photograph the floor and print of and apply the print to the mirror with Mod Podge. Have fun........
What color are the walls in the room? I could consider this first and then decided if you'd like to have contrasting color on the mirror frame or a coordinating color. I have grey/ white floors in my bathroom. When the room was red, the mirror frame was painted white, now that the walls are white, I stained the mirror to look like wood for contrast.
It doesn't have to match perfectly - a complementary color could be nice, too!
Tape the mirror along the frame and paint or spray paint to match.
You could take a spong and a plate add on the plate some gray paint and some white in two piles dab the spong in gray then white and start dating the frame till you get the look you want .
