No to terracotta, that would be closer to your gutter guard that doesn’t work with your bricks and would be the first thing I’d address. You could square up the bricks around the garage doors and modernise the front door screen. The roller doors could be more modern too, although they look fine and what they are.

Hi Teresa, are you painting the eaves also? That will affect your choice. Colours vary and can be very deceptive, but on my screen it’s coming up as a muddy yellow for example, so take this into consideration when reading the answers to your question. I love the look of the gable on the second house, but if you don’t like white as the background, perhaps consider ironstone in quarter or half strength, with the timber in full strength or vv. Luckily it’s a relatively small area, if you really don’t like the colour you choose, a fix shouldn’t be too time consuming or expensive

Was recently like you with yellow. Have just repainted eighteen year old light white washed look brick house (charcoal roof and black windows) that had all dated classic cream trims - garage, front door, eaves, downpipes, patio ceilings etc which I wanted gone. Go to Bunnings or local paint shop and collect all the little sample swatches that appeal to you. Then in my case I bought Dulux A4 size sheets in colours that I liked. You can then compare the Dulux A4 sheets with other brand colours if you want. When you narrow it down you have the option of buying sample pots. I knew I didn't  want white (too light) cream (too yellow) or beige (too boring.) Finally made a choice in between cream and beige and am very happy. Looks fresh and bright, goes perfectly  with the bricks and no more yellow. As you are painting the full house remember the colour you choose might need to be a shade darker than what you think.

The roof is a very big part of the exterior of your house. Faded concrete tiles, even cleaned ones ,will always make your house appear old and dated, no matter what else you do. I would definitely paint your roof, probably in a charcoal colour like monument, as it not only looks modern but is neutral and will complement whatever colours you use elsewhere. If you add solar panels, they will also blend in well. Using a green shade on the roof is the last thing I would do. You would instantly date the house as it was typical of probably the eighties and you will severely limit the other colours you can use.
