It looks like you home has had lots of renovations and changes over the years so I wouldn't be too concerned with getting a new scheme that is completely authentic, but something that works with the elements that you can't change easily. The large bricks were probably a smooth faced concrete block, not a terracotta brick , I am not too sure what the pock-marking is under the window? Can you share a photo of the brickwork near the front of the house? Best of luck, Dr Retro of Dr Retro House Calls https://secretdesignstudio.com/services/dr-retro-house-calls/

I love your bricks too. In fact I would repaint trim colours the same as they are.

I would take the shutters off and see how it looks. And yes to painting them if they are to go back up, paint the windows, the existing painted parts of the porch, gate and the gable all the same warm white colour. The fascia and gutter a warm grey like woodland grey. Some flowering plants will complete the brightening up. You can mKe the whole gable darker, say a 1/4 strength of gutter.

Again , I'm different haha . I like the brick , but it is a bit much , so have something to distract and hide the wall a bit . A large colourful work of abstract art would be my go-to , or possibly a TV or two . It doesn't look like that room is orientated towards that wall , so presumably theres a TV elsewhere in the room , but why not add a couple of secondhand TVs , maybe a 42inch and a 32 , or even 3 -- 42 , 24 and 19 inch . Have 1 on the same channel as the ( presumably main ) other TV I'm assuming is already there , the other 1 or 2 on different channels . Seperate heights too , and obviously different sizes , so its sort of an art installation with moving pictures -- a couple of 2nd hand TV's probably well under $500 , even with wall brackets ; art whatever you spend ( $200 , $1000 , $135 million haha ) .
