There is a big choice of white paints on offer in the paint store. White paints can come with bluish, reddish, yellowish, and even greenish undertones. Which white suits you best? It can be a tricky affair. It depends on the type of paint, the surface underneath, the light in the room and the reflection power you want.
Carefully consider the situation in the rooms that you want to paint. Take some photos in daytime with sunlight and on a rainy day and in the evening. Study them closely and you will see that both artificial and natural light create different colour values. Then visit a professional paint store to see samples of white paint and ask to take some home to see the whites in your own surroundings. Also remember to include he influence of trees that shed their leaves in fall.
