Using lighter colors in your medium-sized room will make it feel more airy and bright.

For your main color, we chose to use 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.

Use an eggshell finish paint which has a very light touch of shine (similar texture to an eggshell as implied by its name). This finish is very often used for walls and is more durable and easier to clean than matte finish. You can consider 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. You would just have to 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. Use semi gloss for trims.
