Just my opinion (from top to bottom):
the red/black is always a good one,
drk blue/black too dark for my liking (not enough contrast for me)
light blue/black is better
blue on blue is interesting (either one)
Red/blue just looks wrong,
blue with red trim looks worse...
The red/wht/blue ones: I like the one with the red on the top (but that's my preference)
The last two with blue on red (blue bottom) and white hood, I'm not crazy about.
