I can barely see the brick in this photo - looks brown perhaps? If you want to move away from those tones, and there's not much brick to begin with, then I'd consider painting it. I would do the brick and siding the same color, or at least, not have the brick be lighter than the siding. As it is, the structure seems top-heavy, so you don't want to reinforce that. I also can't tell your roof color because of the snow. Once the brick is primed, the roof tone would be the only limiting factor. That means the potential combinations are numerous. To narrow down, I'd look for examples of houses you like either online or in your area, and use them as a general color guide. One thought - I'd consider doing a brightish color on the front door, so it comes forward. Right now it seems lost in the shadows.
