Different windows, trim and garage doors would be significantly more expensive then repainting I do believe.

There are some beautiful carriage house style steel garage doors that would look great with your tudor. The color looks faded on your existing garage doors, and that is ruining the curb appeal of your home.

You might not want to paint the whole house, but I would definitely paint the porch railing to match the trim.

The tops of the porch columns, the wood siding, the Tudor battens and the porch railing should be stained all the same color? Then paint the garage door a color that approximates the stain color?

Minimally, stain the porch railing to match the siding & other wood trim & paint the garage door in a color close to the stain color.

I agree with ci_lantro. Also the white trim around the garage doors really draws the eyes there - which you don’t want. It should blend in and match.

Because the garage is large and front and center the garage doors strike me as being the biggest problem. The brown on them doesn't match the brown on the rest of the house. If they are in good shape and relatively new so you don't want to replace them then repaint them a lighter color that complements the stone. But not so light that there is a lot of contrast with the brown roof and siding. But it's better to be two shades lighter than the siding than to try to match it and miss. The natural wood front porch railings should match the color of the pillars, and the front door shouldn't be white. If that's a storm door, get a full view one so the real color of the front door is visible.

You have several shades of brown on the house. Between the roof, siding, garage doors, trim and porch, they all clash. If you don’t want to paint the body of the house, make all the other “browns” work with it.
