I wrote nice detailed post and lost it via this random keystroke thing that wipes out my posts usually right at the end after Ive spent an hour. WTH is that???? Anyway short version - keep all stucco (body of house AND the short wall around porch landing) same color . I thought you said you are keeping it gray? So why are we seeing all the blue and black and white houses? Is that original unpainted stucco, or has it been painted? Deemphasize dormer by changing siding to darker color, get rid of red and turqouise. Stick to 3-4 colors - 1 for stucco (body of house and porch wall), one for roof color (looks to be more of a green-blue-gray?), one for trim (is it paintable?) and possibly nice accent color for door + the cute little diamond patterns . No veneer - keep it simple, beauty is in the original design and proportions. Can the white trim be painted? I could see all that being a dark gray that relates to the roof color with the cement gray left as is. Recommend D/2 biological cleaner for your masonry - I was amazed at amount of algae and crud coming out of my 100 yr old cement house. So much brighter/lighter, I decided to just put on clear matte finish and not paint. If you do paint then mineral paint aka potassium silicate is best product for vintage masonry - some US sources are limeworks.us, Romabio, beeck.com

Computer simulations are only going to get you so far. Time to get a big board (at least ten square feet) and paint some samples. Prime it and apply two color coats to get the right effect. You can move the board around to all sides of the house to see how the color looks in different light. The two colors recommended are very similar. They are both medium tones. They are lighter than what you have, but not off whites. Only you are going to know if they're the right amount of light/dark for you. You can always move down the chip to a darker version if they do end up looking too light. I'm not usually a fan of painting brick, but you don't have very much of it and it does seem to be creating a problem with finding a solution, so do give it some thought.

Suggestions please for paint colors unfortunately the orange stays and luckily it will be in back of house

You have white vinyl windows so I would paint the trim white. The shutters are only on a couple windows so I would remove them. Doors could be anything at that point. I would prefer natural wood.
