That's impossible to tell. You can't get in front of the first mirror to see the "true" color.
Concave
A plane mirror doesn't 'really' form an image at all. The image is 'virtual', not 'real'. You see what appears to be an image. It's located at the same distance behind the reflecting surface as the actual object is in front of it. If a real image exists, you can always put a piece of frosted glass, photo-film, or tissue paper where the image is, and capture it. You can't do that with a plane mirror.
A CONCAVE mirror is a mirror with a reflecting surface that curves inward.
