I don't mean to say "re-invent the wheel," just suggesting something simple: change of envelope color, envelope style, etc.

If so what color should I paint the roof and wall?

I usually charge $20-50 for the patching you described, should be 20 minutes(or less).ALSO, I strongly suggest you use factory premixed color, I use Home Depot Behr Swiss Coffee, it makes it easy to blend future repairs and when we have turnover, its just quick freshen up coat, without having to go full on multiple coats of paint and primer, or set up for spraying, etc.

They have their own CMA form and want the pictures in color, they also want it typed, not handwritten.

Jonah Section 121 exclusion is a little more complicated its a great incentive can you give us some more color and dates that would help with analysis. 

Consistent 24% returns are rainbow colored unicorns.

Then I bought a bunch of colored tacks.

Make sure you pick light paint colors throughout, get rid of any heavy/dark curtains and such, upgrade or install bright light fixtures where needed, etc.This all comes from my own experience in Southern California.

There's all kinds of reasons not to allow it (i.e. they rarely/never do a good job, there's no incentive for them not to cut corners since it's not really their house, they could get hurt doing the work, they tend to pick weird colors, if the work doesn't come out good you have have little/no recourse, etc). 

Red brick and green accents= Christmas colors too!
