I don't think your pics are a color disaster, but they're your pics, so I'll try to tell you how to get them the way you want. There are 4 reasons the pics came out warm.
1. Your ambient light was probably incandescent. 2. Your ambient light was probably too much a part of your exposure. 3. The yellow walls turned the reflected light yellow. 4. Your WB was set to flash.
When shooting raw, I always use Auto WB. It usually works well, and if it doesn't, it's easy to fix in PP. So in your software, try setting the WB to incandescent. You might have to adjust the sliders some to get the look you want. There are other ways of adjusting the WB as well. Such as setting a grey point. Also, you may or may not want to adjust the saturation, depending on your taste.
1 and 2 could have been fixed before the shot by using a faster SS or by gelling the flash(putting a yellow piece of plastic in front of the flash.) But since you shot raw, you should have no trouble "fixing" these pics.
Now I'll let Brian give you a better answer
