which size would be best as a poster above a desk?

That will depend on the specifics. If you are looking to utilize this chart as reference in a bedroom environment, then going with either the 15 x 20 or 18 x 24 option is a good choice depending on the wall space available. If this is for a classroom environment then maybe going with the larger 24 x30 chart is the better option.

Are the semimetals featured as being blue or black? (Just asking cause the pictures show two different things)

The Semimetals are blue as in the primary image. The Images showing black must be a faulty render output. Thanks for bringing this to our attention.
