choosing paint for grady's bathroom

gradys bath WILL be painted by the end of the week.
(at least, i hope so...)
i want a warm gray that adds some depth to the wall, but i don't want it to be too dark, because the room doesn't get any natural light.

last week, the second pendant over the toilet was installed. more progress! (because of a code that doesn't allow a hanging fixture to be within 3 feet of a shower/tub we didn't install it before we moved in.) it definitely helps with the amount of light in here. to UP the light a bit more, i have since swapped out the 60 watt incandescent bulbs for 75 watt warm fluorescent ones. (by the way, am i the only one who HATES the "cool" or "daylight" fluorescent bulbs? ugh! i think they are awful. remind me of being inside a 7-11.)

 i also replaced the flush mount light with a simple 3-light spot light, which made a HUGE difference! i actually love this flush mount light, and will repurpose it somewhere else in the house...

the new light:

 found for $5.99 at ikea...and that included the three bulbs! how could i resist?

but anyway, i am getting a little sidetracked, aren't i?
we were talking about paint...
ok, so the plan is to get a paint color that adds some subtle color, and supports the masculine feel of the room.
here are the colors i sampled on his wall:
this is the wall above the vanity:

  all colors are benjamin moore: cumulus cloud, stonington gray, la paloma gray, cumulus cloud @50%, seattle mist, balboa mist.

this is the wall opposite the vanity. as you can see, it seems a little darker:

for comparison, here is that same wall, after i replaced the flush mount ceiling fixture with the ikea spot light:

my favorites are balboa mist, cumulus cloud and cumulus cloud at 50%. i also really like stonington gray, but i like the warmth of the others just a tad more.

before i swapped out the ceiling light and changed the bulbs in the pendants, i was definitely leaning towards "cumulus cloud at 50%", but with the added light, i think the room can handle the slightly darker "cumulus cloud".

what do you think? which paint is your pick?
