Photos of the exterior would be helpful.

Definitely YES!

As for the question you've asked Light pink or light lemon color to the walls would make it look good and Dulux paints. Dulux because Asian paints are mostly when used on decorative walls and for a simple light color Dulux would be the better option and pocket friendly compared to Asian.

morning glory is the shade that will have a beam of lightness when sunlight enters the house and the most common mistake some people do is just play off white blunt to all the walls, but I suggest u add a colour of Prussian blue or crimson red with the morning glory. hope it helps. thank you, do review us.
