Kitchen Paint Color and Curtain Advice?

I need help with what color to paint the kitchen walls and the color for curtains? or Roman shades? I have light golden maple wood kitchen cabinets and ceramic 12x12 floor (called Caribbean Slate from Lowe's, it's a light neutral tile, which has gray/silver with green hues mixed with splashes of sand, beige, and cream tones- so neutral goes with practically anything). I am thinking of getting a darker granite counter with some black in it, and stainless steel appliances.

The color in our dining room, which is separated by an archway, is a chocolate beige (Benjamin Moore Big Bend Beige). I'm thinking of just going with a beige to play it safe, but want to have color so thinking yellow? or gray color w/ slight green undertone? or green/sage? or bronze brass reddish color? I'm all over the map and not sure what direction to go. I could really use any help. Thanks.
