Striking house. Have you already talked to a stone mason about changes to the stairs that will meet current building and safety codes?

cool house!

I'd be tempted to do a sheer charcoal over the stones, to tone down the pink while also toning down the contrast. or if you were unsure, darkening just the pink stones only. start with a less noticeable area and see if you like the effect. you can always limewash over that if you don't like it.

I love your door. suggest painting the trim white, and choose a bold pop of color for the door. once the pink rocks are toned down, you could choose just about anything for that front door.

I like your idea of the black iron railing, that will look amazing.

Please do not do anything to alter the color of the stone or paint over it. That is arguably the most unique feature of your house and future owners will thank you for not making any permanent changes. My suggest is to embrace the stone colors and paint your siding and trim I’m complementary shades. I realize that cool grays and black are trendy right now but not every house supports that.
I don’t think the brick steps will be a loss and if you want a more modern feel, I’d go with dark trim around the windows and along the roof, something like a dark brown or bronze. Replacing the front door with a painted one with some windows would add some contemporary flair as well and you could look to do something different with the railings on the steps.

Since you have white vinyl windows I would paint it all white. That will simplify the overall scheme and highlight the stone. I would also paint the wood colored trim on the door- keep just the door wood colored.

Thanks for the comments, everyone! No, I have not contacted a stone mason about building code. As existing stair foundation seems solid, thought to just cap with concrete slabs to keep costs down, make the stairs sturdier and reduce the redness. I like the idea of painting trim along roof a dark brown. Should I do all the window trims too, or would white trim help give depth? Pinkness of stone will hopefully be reduced with new stair colour and darker trim - staining stones will be last resort because of cost and keeps character and interest (to Jesse's point). Any one know how expensive/difficult it is to paint fascia trim along room and soffit? Or is it better to just replace?

I think if you just tone down the grout, the stone will look fabulous as is. Maybe a grey or greige will do it. It would be a meticulous undertaking to make that happen but if you're like me when I've been renovating houses, when I don't have the money I have to find the time. Look at the difference changing the mortar made in this discussion https://www.houzz.com/discussions/6003264/tuck-pointing-fireplace-to-change-mortar-color#n=7 The OP went a different direction from you, black mortar to lighter but you can see the change in the stone color once the mortar is changed. I think you should try a sample spot and see if it reduces the pink. IMO, the pink is totally mid century, so I think you should in no way paint that stone.

Yes, the white piping mortar is a huge sticking point for my husband. Given the effort required, we will try all else before attempting to remove - and agree with you tozmo1, will try to keep the stone - pink and all.

I hope your house is just as fun on the inside. I absolutely love the roofline!

@jannetnguyen just to be clear, I was recommending painting or staining the existing mortar rather than replacing it. That's what the poster wound up doing in the link i included. Good luck!

I didn't notice that grout before, that is a bummer but if it's very porous it may be tedious but not impossible to stain. The soffit and roof flashing look to be aluminum which means that can be painted. Not as nice as factory finish but not the end of the world. Id leave the soffits as is before painting them. I had the same dilemma (although mine are Hardie) and I went with an off white paint on them with dark bronze fascia. If the windows really are vinyl as someone pointed out, it isn't impossible to paint them. I would recommend a product called Plastic and Vinyl NT which is an XIM product. I've used it on my vinyl windows which haven't be replaced yet and it works great.

DO NOT touch the stone use a color from the stone for the siding and I have no idea what the issue would be with the railing and I hoestly see little of the pink so not an issue and IMO the nicest part of the house to honour the style
