the green is by far the nicest color there.
but, i think it would only work if the car was completely mint body wise and finished looking.
(didnt look at pics of your car as it stands so maybe it is?)

i dont think it would work with rough body work or weak wheel choice.

if you can narrow it down to even two colours,
dont be too spacific, say green and red instead of specific colors for example,
then off those two colors get a few swatches of differant shades and see which you like at that point.
