are you open to repainting the brick or does it have to stay yellow? If that's the natural color, fine (I thought it was already painted). perhaps a good power washing would help brighten it up a bit. I love the leaded windows off to the right. don't ever change those! normally the stucco portion is light and dark contrasting color goes on the wood trim&shutters. if you could do the brick in a dark gray, you could do something like this (except I'd pick a darker trim color.)

I usually have an 'each their own' perspective, but when I saw this, it saddened me. All that beautiful architecture molested by the idea of renewing and lightening something up. I totally understand the need to make houses more efficient, but why try to make a tudor what it's not... sell it and buy a different house! That original brick work had it's own natural colors and was beautiful! So was the diamond lead glass windows in the front that were not spared! I only hope as Debbie Downer mentioned that the appropriate methods were used because masonry is meant to breath. Liberties of paint shouldn't give the assurance of improvement. I feel a loss of culture and character when I see all these beautiful thing that lasted the test of time, covered up. It's like people who paint over the amazing grain patterns of non-wormy, American chestnut trim to modernize the interior.

Aren't most Tudor homes "mock" LOL? (Although I loved the "real" Tudor homes when we visited Shrewsbury in 2019.) Mine is a Tudor style too and I love it. And I live in Toronto so we don't have any genuine Tudors because...Toronto didn't exist during the Tudor era LOL. Agree that cream vs white is the way to go. It looks good with the rendering and half-timbering all the way across. My area of the city has lots of these Tudors and people have painted the rendering all sorts of colours - white, cream, tan, gray. IMO the nicest look is cream with a dark warm brown e.g. Benjamin Moore's Tudor brown for the half-timbering. I'd add some diagonal half-timbering too, just because I think it looks good. Where it makes sense, paint any white or dark gray wood in the same dark brown. Maybe your garage door just needs a coat of paint. Paint or stain your front door dark brown too and it will fit in. Your yew hedge will give you privacy once it's filled in. Not sure what your plans are for landscaping, but in the meantime if you had one large planter it would give your house a lift. Depends on your climate, we don't know where you are. Very nice house.

Leave the brick and lighten the stucco, siding and trim. You might pick up a light variation of one of the colors in the new wall for the trim.
