Honestly photons are terrible for decoration, they do not display decorations correctly, not sure why people even used them in the first place.

Electrons display perfect decoration color and behave identically.

These have identical decoration values, (blue/red smudged together)

As you can see photons discolor greatly.

NOTE: Energy particles still aren't seen in decoration editor, so the main issue of decorating them is a bit harder, although still VERY easy to '!set type blah elec' after decorating a solid.
