I want to paint the wall of my bedroom like below. I have enough painting skills to paint the whole house, straight. So I believe I can pull this out. But I wanted check about the methods.

• For the color tones, can I use those 2 edge colors(dark blue & beige), and white to tone them?
• What are those colors?
• What kind of tools I need? A regular brush for all of it? Or brush for the edges, and a roller for the insides?
• What kind of paint I need? Wall paint? or should I use some kind of
  oil paint?
• Is this doable for an amateur?
