I like the brick but not the stone. I would leave the brick as is & remove the stone if possible since I don’t think painted stone ever looks good. I would paint in a color complimentary with your brick & either remove or paint the wood trim around your entry the same , but I see that it continues down alongside your door so I’d have to think about that. Definitely a larger lantern above the entry.

I agree that painting your stone is not going to give you an updated look. I would either embrace it or remove it entirely. Your greatest impact is going to be in painting the stucco and trim, front door and garage door. All of those except front the front door should be the same color. I would recommend picking a warm gray or taupe color out of the stone. This will both downplay your stone and bring the house into a more contemporary pallet. For your front door I would consider a dark rich color. As K Lawrence said, go big with the light over the front door; perhaps something with simple lines on a bracket.

As far as painting the brick, I like your brick, and would try fixing the color of the stucco and trim first and see what you think. But this is also a house that wouldn't look bad with the stucco, trim, and brick all painted the same color.

Remove stone, repaint brick and house, same color - white or grey. Change front door. Paint it another color- red.

The brick looks cool, the stone doesn't.

Warm greige paint for the house, don't paint the brick or stone. The columns of brick are part of the striking design. The stone was probably added later.
