Color Dilemma - Help!!!

Here is the color dilemma...

With baby No. 2 (Ms. T) coming in January, I am playing with room paint colors.  Ms. Diva's room (soon to be both girls' room) is still the bold Camo job that Mr SD's son and I did while he was living with us.  I am starting to feel that the room is way toooooo dark.  Especially now that Ms. Diva is having fun playing in there with her toys, and the dark colors we used soak up a lot of light.  I will need to prime the walls (and ceiling) before changing up the colors. 

The girly colors have been more fun to play with than I had thought they would be.  As long as we stay away from baby pink.  My thought was to use a light purple with an aqua or teal accent wall.  I included the ceiling in the accent color, but as much as I like color on the ceiling I think plain white will help to lighten up the small space that only has a small window for natural light.  The window is definitely not as big as in the example room, LOL!

I switched it up for this one, and used light purple as the accent.

Which one do you like (1, 2, or 3)?  Or, what other thoughts do you have, or experience I should know about?

I would love to hear your thoughts!
