Greek interiors

[Musivarius]

I'm working on a pebble mosaic floor for the Bedford festival and wondered if anyone can point me in the right direction where best to look for some information.

1. I want to know if we have any idea how high status house or even palaces may have had their walls decoarated/painted? It needs to be anywhere between 5th BC - 3rd BC.

2. Also information on flooring for temples and again wall decoration (if any).

Thanks
