I think blue lights would be cool! But the bulbs used for tank lights will not grow your plants, they need natural sunlight. It does not need to be direct sun for the sake of the fish but natural sunlight will grow the plants. I'm not sure what lighting is less stressful for fish but I have a white florescent light for my tank and it really brightens things up, so if you really want your tank to pop, a personally like the white florescent best i brings out more color in my opinion. :)
