Hello!

I am having some really difficulty figuring out the proper way to pick colors for my kitchen.
At the moment everything is - white cabinets, dark forest green countertops, mint green walls, with big square white flooring with little green squares (if that makes any sense).
We are just wanting to replace the flooring because it is not in the best shape and can't afford to replace the counters. But what color do I go with? Do I find flooring that is green or something neutral with green tones? BTW, we are keeping the walls the same color.
Help - if you can.

Sounds like you have enough green going on as it is.
Take some neutral tiles and lay them down to test, any tile store will have some samples (even if they are mean it shouldn't cost more than a few bucks). Try light and dark samples and look at them in the evening when there is still a little natural light but the main light is from bulbs and see what works, you'll know right away.
