Looks much more gold now and if it is, any colour would look cheapy on it :sweating:
Gold pairs mostly with tones of itself or a proper tone of silver maybe. Also, transparent stickers with outlined only letters but then it would be some rather big stickers :fum:
Original toyota "Hybrid" badges (if they exist) would be perfect :winker:
Does this represents better your color?
