i like a light grey look
or you could do a dark greyish color that has a shade of a blue green

Continuity is key. You really have two choices:

1. Choose a darker or lighter shade of the cabinet color, if you want the clean conservative look.

2. Choose a color from adjacent rooms or fabrics to create color flow/continuity.

Try to avoid introducing a new color unless you plan on reflecting it in other elements, i.e. countertops, large paintings, window treatments. Each new color needs to be repeated at least 3 times, to attain balance.

If you choose an alternate color, rather than shade, make sure it is muted (grayed) like the cabinets. Any color will work, so long as it balances with existing colors in the home and has enough muted grays in it. Try Benjamin Moore's Aura color selection deck. It has many colors but any two will work together simply because the shades are balanced.

Aside: I love the Cabernet color you're painting over. It's just a bit too bold. That same color muted, would be a winner, if it balanced with other elements in the home. By default, I take tips from nature. Notice the soft garnet tone in the granite. So right with the muted grays.
