A bedroom should make you feel relaxed, so I think it might be a good idea to paint the wall light
blue. Blue can bring peace to your mind and body. As a Grade 9 student, you always have much
homework to do and feel stressed easily. So blue is the best colour. As homework and exams make
you feel tired easily, you need energetic colours in the bedroom. You'd better put some green plants
in your bedroom. They can make the room full of life and make you feel energetic.
I hope my advice will be of some help and that you will enjoy your new life!
