I would do a cream to go with the stucco. The existing white fights with the cream stucco. Black would fight with the brown wood elements. You could probably get a brown/bronze that goes with the wood.

Tudors traditionally have diamond panes. I'm not a fan of grids. I'd do none.

Here’s what I’m looking at.

This is the one I really like.

Here’s my kitchen currently with white windows, and then in the visualizer with black windows.

Bronze or Dark Tan windows

The mock ups you made are great and create a strong case for black windows. Your home is not really tudor style. It just happens to have some diagonal accent trim on the upper house. So don't be wed to an idea of tudor. Do what looks right for your home. I think you've got it.

Tudor.

Bronze.

The Tudor with a Dutch Colonial roof seems all wrong. I'd consider eliminating all the diagonal timbers.

Those aren't Dutch Colonial roofs, those are Jerkinhead roofs which are Tudor.

Brown windows if you go dark.

Bronze windows, no black.

SO IMO not Tudor except for the trim do take it off then see what the house looks like IMO it will be a lot better. Then dark bronze windows a darker color for the rest of the ecterior not the brick and IMO no grids since that exterior is already busy even without the trim. Keep that round window on the right lose the octogon and then that entry needs some huge fix and what yard you have needs lanscaping.
