I would suggest a clear, light yellow for the siding, white for the trim and garage doors, and shutters the same color as the roof.

Check out the top rated home exteriors on this site for inspiration. Since you say nothing about what style or colors you like, but do say that you have trouble making a decision, it doesn't matter what we suggest. Just point at something you like and do it.

i think you need to add some color, the home blends into the surroundings with the earth tones, Try using a couple shades of gray, one little for the house and one darker for the garage doors and then using a color for the trim such as a deep charcoal blue or a deep cranberry. Then add some foilage that brings in color,

This is a very nice home with enormous potential. I would do a tone on tone ( sage green with a few shades darker for trim. I would add lots of black wrought iron details ie: large black hinges on shutters. Wrought iron window boxes that fit acroos the entire width of the windows. In between the windows on the pavement I would create a little sitting area with black wrought iron furniture and large potted plants . Two large black urns on either side of the garage doors. Fill all pots with vibrant flowers and volia! a magnificent home. If I had some extra money I would not hesitate to put an ornate wrought iron fence between the garage and the edge of the driveway to make a court yard with a large ornate two door gate in the middle. This would give you more space to add a tiered fountained in the middle of the courtyard you have created. Great curb appeal with extra privacy at the front. Best of Luck with your efforts.

Not really seeing the house here, just the drive. Can you take more close photos and repost? Thanks.
