I would not go for a bold colour in a kitchen unless you are looking for the stricking look as u walk in. I would choose a cream or khaki colour.
Blue Yellow Green ECT.
BLUE
purple goes best
The color does not matter as must as the size GB and 320 is the current best. Most PS3 are black and putting anything on them with have a slight reduction in the ability of a PS3 to cool and shorter...
Green brings a energetic, bright, and happy feeling to your room
