I like the third one, sand white.

I like obelisk. The lighter tones read "pink" to me - perhaps just the color on my monitor.

These don't have the undertone you want - you need something with a golden undertone to play up the yellow elements of the floor. Try sw believable buff or a tone deeper with whole wheat . . http://www.sherwin-williams.com/homeowners/color/find-and-explore-colors/paint-colors-by-family/SW6120-believable-buff/

I agree with Leslie the Sand White is good.

From what little I have absorbed over the years I understand that if you want to "play down" a certain color you do not want to add its complement (across from it on the color wheel). Green is opposite red so.... avoid any color with a green undertone. However your granite is lovely and has green/gold/gray/sand colors on my monitor. Do you have an extra piece of tile you could take with you to the paint store? Maybe you could try to match the gray. I wonder what a true gray would look like.

Thank you for the suggestions so far. This color would likely be used in our entry way, upstairs hall, living room, kitchen and possibly formal dining room so we don't want anything too dark.
