Standard choice is Intense Black, Adrenaline Red, or Yellow Shock. These are what are listed as "Classic" panels, and one set included with the price of the bike. All three are glossy, and molded-in-color. That is, if you scratch it, you won't see another color underneath.
All of the "Epic" or "Exclusive" panels are painted (and some add decals), and are an upcharge.
The rest of the plastic panels on the bike have a texture (called "graining" in the plastics biz) which is similar to a fine sand. This is what gives the rest of the bike the matte sheen. Only deviation from this are the large vertical side panels that your knees rest against. These have a raised "diamond" pattern, which aids in grip while riding.
Hope this helps.
