I think this beautiful bright bedroom has been made cozy and characterful by using vintage pieces and a warm accent color palette. The flooring is soap washed, which makes it very light. The walls are painted in an off-white, enhanced by the white linen curtains* and the white fabric pendant light.
The bed is decorated with a beige linen duvet cover* and a mixture of brown and beige pillows. Combined with the autumn branch and the warm tints in the art print this makes the palette very warm and inviting. I love the vintage desk in the corner as well, which combines so nicely with the art print and the white table lamp.
