Search "color block" in Exterior photos on Houzz for examples of multi colored inspirations. Here are I few I thought were interesting.

any of these colors should work. I also like darker trim color options. any of the sage greens or the warm colors will work. you could also do a combo of 3 colors. leave the stone work as is, and work around it. bringing in some darker tones for contrast would look great. I suggest looking at pics of craftsman bungalows and other split level brick/stone exteriors, to get ideas. I would not paint everything one color. that will be disastrous. No pink/peach shades. no light gray, and the green should be a nice sage tone, not a mint green. I like the one in the lower right corner, using the adobe red for the door

I think your home is pretty eye-popping now, I would definitely be slowing my stroll to get a better look, but I can understand wanting a cheerier color if your environs tend to be pretty grey. The current color scheme does seem to suit the surroundings. Is there a color you are leaning towards? Would you want the whole house to be the same color or have color-blocking as you currently do? Are the windows to be painted? What colors are "cheery" to you? When I first saw your house a forest green came to mind.

I guess I didn't say that I am trying to deemphasize the brick. Not sure if you can tell from the photo but they are Roman style bricks, lacking the interesting dark colors and white stain of more traditional flat brick. It seems like blues and greys would make those bright pink and orange tones pop. My original thinking was white with dark accents. But I do like the dark exterior colors that are popular now. I worry that the dark colors will just make the bright pink/orange really stand out. Ultimately I guess I am looking for the house to look fresh without changing the good bones that it has. I am trying to embrace the look of the brick. Someone want to talk about how to tone down the brick without painting it?
