help with color choice for my high rise condo living room

Nice condo!
Another vote for a warm gray color.
Sherwin Williams Modern Gray or Benjamin Moore Revere Pewter would be nice choices that would compliment and not compete with your art.

First off- I don't push and/or suggest color for the most part because it's such a personal thing; and to some a real "statement" of them- if you catch my drift!
But, I do have an opinion here-
Highrise condo living tends to have it's own decor style, not always, but generally speaking.
I like the premise that it's about the furnishings, accessories, and features. Not the dwelling itself. Bring the collection of color in with the afore mentioned items (which you have mentioned)- and de-emphasize the walls by keeping them white. Bold statements can be made with trim painted high gloss black, such as baseboard, doors and casing. Create intimate lighting moods with coved crown that is backlit with rope or zenon strip lighting.
For example:

^^ love the second pix and the color scheme would work well with the kitchen cabinets.

I would go with a sage green color. it looks like there is some green in your art work, also I thought I saw some green in the pillow on the couch. Look at the colors that you have elsewhere in your condo. I attended a seminar by a designer and she stressed that your home should have a color palette of 3 to 4 colors so that you can move accessories from one location to another. there are some really great colors in the art work. I would look to that for inspiration!
