I like your house color as it is; very craftsman-like. I do think the garage doors should be painted so that they do not stand out and call attention to themselves. I think your front porch is lovely and should be where our eyes want to go. I definitely agree with Patricia...white is not a good choice for this home.

What about when the hydrangeas go and the Montauk Daisies take over Kidding!! I like the idea of carrying the sign color to the door - that could be very pretty. Does the sign color look good with your siding? I love the Dusty Mauve @houssaon posted. I haven't seen that before - may steal that for our front door!

Looks like large pavers. We live in wet winter country - PNW so moss etc is a routine thing here. We use the product Wet and Forget on our smaller pavers which works on moss & grime pretty well. Not all moss is green - it’s black mold looking too. Wet & Forget comes in concentrate or a sprayer container. Needs to be put down when pavers are dry & be able to stay wet for @ hour - so no spraying in sun or heat. Rain comes & washes black away & moss dies so it’s not immediate result but is seen working after the first rain. Not sure how successful this would be in less rainy climate. We buy it at Costco - product is popular here. We did pressure wash our pavers once using a round attachment that gives a much softer wash than the angled hard spray of the angled spray point of pressure washing. We were afraid the pressure washer would lift all the sand filler between the paver joints. ETA: we’ve never sealed our pavers but it is done by some. Need to clean first & I think it’s not permanent so must be redone every few years.

No accent wall - coffee table + art + accent colors for throw/rug/different throw pillows. Add some texture with the throw + pillows + window coverings. Adding something in stone + a plant. All of the foregoing helps make a room look "cozier." Emily has made a nice image already - so, I decided to make one to see what the room would look like if you replaced the existing rug with a new one. I'm not sure why it put two pieces of art on the wall by the floor lamp (looks too busy) - I only wanted one! Also, I decided to try a floor lamp + move the plant out of the corner just so you could see something a bit different than what Emily posted.
