I'm 14. What color schemes do you approaching the best for a very small room? Feel free to include any other thinking and suggestions. AND NO OBNOXIOUS ANSWERS. THOSE DRIVE ME CRAZY!
1. Blue, green, white
2. All white with bright, bright pink, sickly, green, blue accents
3. Blue, washed out, white
4. Pink, yellow, white
For number 2 I be thinking things like bright green sheets, bright blue kerosene lamp, bright pink rug, etc., but white walls, furniture, duvet cover.
What do you like best?
Answers:    I'm going to influence #2. You're less credible to get tired of it and not be capable of do anything to change it.
i close to 1 and 2but not 3 and 4 those are weird. for 2 i want to do something resembling that to but instead of white black
