I would go with a gray roof. Colonial Slate or Driftwood.

I would go with gray too, but, I would use charcoal roofing.

My DH is also red/green colorblind. It makes choosing colors VERY tough.

I would also do a dark gray/ charcoal roof with very slight color variation. The charcoal black color looks a little dark on my screen, colonial slate and drftwood are nice.

Here is a mint green house with black shutters, the colors look nice together. Be sure not to skimp out on the shutters, make sure they look like they are big enough to actually cover the window if closed. That would mean no shutters for the bay window.

A bigger porch light would be an inexpensive upgrade with big impact.

Lose the shutters please , A gray roof is perfect then wash that siding and paint the siding and the concrete the same and I love this color with brick in fact you could do the same for the trim too just like the pic . Then add some nice big planters in front of the concrete and please paint the down spouts the same as the siding . I do not like the mint green you have now

Patricia I cannot see that color. To be it looks blah. Good suggestion about the shutters.

sunnydaze, my husband just pulled a clear plastic dip container from the fridge to look at the label on the lid because he couldn't tell from the side if it was guacamole (green) or hummus (tan).

Made me think of this thread :)

Sunny daze, the color Patricia suggested, subdued mossy green gray, is one of my favorites with the reddish tones on the brick. You could go a little darker but that tone really works with the brick. The driftwood color is a good neutral color. It's probably what I have, or maybe slightly lighter on my home. It goes with most everything and has enough variation in color.

My dad was red/green color blind so I understand. We had to help him pick out clothes every once in a while. Bring someone with you to pick out paint or new siding color is my best suggestion, hopefully someone good with color. If you go with a tan color of siding be sure to pick out a darker tan. I've seen some end up with a pink hue to it that you don't notice until it's all up. Also, you shouldn't pick out green, you may end up with a mint jewel tone that would not be good.

If you’re up for changing the entire color scheme you could do a black or charcoal gray roof with the body (siding and brick) a light gray, and the trim in white.
