Maybe paint, but I think landscaping would make the biggest difference. Create a curvier look with a rounded bed in front of the two windows on the right. Add some vertical height between the two windows with a small tree...maybe an Amur Maple. Keeper it far enough from the front of the house so it doesn't crowd up against the wall when full grown. In front of the railing by the pront porch, add depth with a walk with a curvy walk and plants with a variety of heights and set so they are not in a straight line. Your local nursery can help you with plans.

Even getting an updated color on shutters and doors, no more beige, how about indian red. And then plant softer bushes, like Burning bushes, and other bushes that turn colors.

Thank you
