Agree on all three points, although you could probably survive keeping the peach, white trim, no shutters, and some new front door color (cranberry?)...

Is the house body peach?

extend the tan in place of the peach. paint all the trim white. either leave the green door and shutters or paint them white.

I think a decent quick fix would be to paint the corner boards the same color as the body, those stick out to me the most.

If budget further allows, you could paint all the trim an off-white.

Change the peach and teal to a medium sage green and the door( all parts) to a dark red. Remove the foundation plantings and replace with more plant varieties and shapes.

The body of the house is tan
