Nice-looking house. A white gutter would look continuous with the white trim on the carport. A brown gutter would not show dirt streaks as much as white gutters sometimes show. Since you are only putting gutters on the easily reached area in front, it could be pretty easy to clean them off when you empty out leaf debris, if they do show dirt streaks.

Thank you Never thought about streaks putting them in the back on the upper

Streaks are annoying. Climbing up on a ladder to clean off streaks is just one of those house jobs that shouldn't ever have to happen. Better to match the gutters with the non-white roof color.

Gutters should match the trim color, leaders the siding color. Neither are design elements and should blend in, not draw attention. They are essentially a necessary evil, lol.

I need them due to lots of water issues in the back

The drop edge will be covered i like the way it frames my roof
