Hmm...look up flame test. There are more ways that an element has "color" than simply their powdered form. For example, how do you designate a "color" to hydrogen? "Clear?" Instead, it has to do with the energy that the atom releases after its valence electrons have gained and then lost energy due to being excited by a flame. When the electrons are excited, they jump to a temporary excited state, where they lose energy. This energy is in the form of a photon, and translates on a larger scale into a specific type of color. H and Li are red, Barium is yellow, and Cu is green (I think). Try looking up "flame test" on google.

When talking about the color of the elements, do not include any oxides, chlorides, carbonates, etc. The CRC tables tell of the color of the elements as the discoverers isolated them.

Look them up on Wikipedia. This has a description of all the elements.
