Couple of thoughts here. NIX the hunter green.

It is passe for sure but the sage sounds nice. Your existing colors are very bland but a dark accent might make all the difference, especially since the floor is light as well.
I have seen two awesome "dry mustard " and sage combinations recently as accents which are very rich together but not sure if that could work with your back splash. When the budget improves you could trim that back splash away with a utility knife and tile it for more accent. Or cut it away and paint it and just run a wallpaper border above the splash. If you stay with soft shades you may want to eventually darken the counter tops for more contrast. The contrast on the island would be a winner for sure.
My kitchen is a 7 x 9 galley. Just repainted all the 35 year old OAK again with a fresh coat of bone MELAMINE for a clean look. Then tiled the back splash to pull up the dark granite look counter. We used slate brown paint on one wall to give it some pop and wrapped the brown onto the bulkhead at the ceiling where I will install mini pot lights in future. Then I inlaid slate brown mini tile as a border in the back splash. Total makeover so far, less than $200 although we had done the handles prior.
FYI on a tight budget, you could also paint the counter with melamine for a fresh look. The second shots here a 1/2 bath room that used to be hunter green. We saved the wallpaper border, painted out above it and converted to sage. The hunter green still remains in the flooring...future project. The counter is a light slate which pulls in the green beautifully...IMHO
