Since your room is smaller using a light and pale color will enhance the light and the space in your room

It is great that your main color, is 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.

If you had to paint the studio you should 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
