Since your room gets plenty of sunlight your color options are quite broad.

For your main color, we chose to keep white/off-white as it offers a fresh, clean, feel to the space. White and off-white colors are often a favorite for walls because they are light, neutral, and match most color schemes. They are known to make rooms feel more airy and spacious. For your accent wall, we chose to use gray because it is neutral and seen as elegant and classy. It compliments many colors such as white, blue, and yellow and works well as part of a color scheme in any room.

Use a matte finish paint because it will be helpful in camouflaging those surface imperfections such as bumps and cracks as it does not reflect light. Just be careful because matte finish is more difficult to clean. You may also need to touch up scratches or marks by adding more of the same paint in the future.
