The stucco is sage green, yes?

With sage I like sky blue, violet (the flowers of the sage plant are vivid purple--can't argue with nature!), plum, brick red, reddish brown, burnt orange...

Do you already own the home? A better picture of the front entry would help.

Here's a better picture

The roof colour would look good as well.

I would paint the garage door and the front door a dark color or if they can be stained a dark color, but I would keep them the same color.

If you aren't going to paint the garage door or are not willing to the house looks like a sage tone. I'd pick Mature Grape.

That is I believe they are not real wood and can't stain.

I agree with Lindsey there -- I think a color similar to the roof would be nice. It would connect the color palette of the exterior together.

Orange, yellow, lime, turquoise, hunter green.

The front door welcomes u & is the jewel of your home.

make that jewel an amethyst ;)

Houzz is showing a lot of purple ads. Yes if u want that.
