I actually prefer the darker wood looking plate (that you show with the green) on the red one. I like the silvery plate on the green. Personally for myself I would choose the darker one on the red but for someone with blue eyes and silvery or blackish hair I would choose the silver on green (or silver on blue or plain blue). For someone with reddish hair or blond I would choose the bottom one... the golden brown on the green.
Just to complicate things, lol. I always consider hair color and skin tones when it comes to colors of clothing or accessories
