It is funny, but I did not change the garage door color. I used MS Paint and it did weird things to the roof too. Looking at it here, it seems like I made the top part brown.... I'd either do the garage door with the 2 light tones or keep it all white. I'd paint it last to see how it looks white first with the new house color. When I was working on the mock up, the lavender was either too strong or too light. I went with too light because the next step up was garish. Our lavender is sometimes very subtle, but when you see the nearby white, you realize it is not white too. It also looks different as the light changes throughout the day. I'll try to take an exterior pic of our house tomorrow. The landscaping needs a major trim, but the blooming trees out front are at their best. I work from my office Thurs-Sun and from home Mon-Wed (much fewer hours), so can do some work on them in the a.m. and take a neater photo ;) Although, it sounds like it is raining outside at the moment...

The Home Decorating forum is really good with color, too (especially when working with a bunch of neutrals and various textures), so try to cross-post over there, too. :-)

White Dove has to be one of the most popular white around, along with Simply White and Cloud White. I often check out the Benjamin Moore's Colonial Williamsburg collection when I want to change colors. I found a white called Capital White CW with a slightly creamy undertone compared to White Dove. Look at BM colors in this link: https://www.benjaminmoore.com/en-us/color-overview/color-palettes/most-popular-colors Have you browsed Houzz white exteriors to see what is featured? (Sometimes they mention the exact color in the write up.) Here is one house with a brown roof - BM Ballet White - not white white, if that is what your leaning toward. Good luck.
