Though your natural instinct might be to stick with white to make the room seem larger, adding some colour here and there will add dimension to the room and, as a result, make it seem bigger.Try using the 60/30/10 rule. Make 60% of the room a plain colour like white or pale grey. Make 30% of your room the secondary colour like dark grey or pale blues greens or pinks. Make 10% of your room a bright accent colour.  The key is to find a balance between having too much color and not enough. For example, offset white walls and a white bedspread with colorful throw pillows and curtains.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/18\/Decorate-a-Small-Bedroom-Step-5Bullet1.jpg\/v4-459px-Decorate-a-Small-Bedroom-Step-5Bullet1.jpg","bigUrl":"\/images\/thumb\/1\/18\/Decorate-a-Small-Bedroom-Step-5Bullet1.jpg\/aid3566522-v4-728px-Decorate-a-Small-Bedroom-Step-5Bullet1.jpg","smallWidth":460,"smallHeight":334,"bigWidth":"728","bigHeight":"529","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"}  Don't be afraid to mix and match colors. Sticking to only one or two colors will make a small room look drab.    {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/5\/5c\/Decorate-a-Small-Bedroom-Step-5Bullet2.jpg\/v4-459px-Decorate-a-Small-Bedroom-Step-5Bullet2.jpg","bigUrl":"\/images\/thumb\/5\/5c\/Decorate-a-Small-Bedroom-Step-5Bullet2.jpg\/aid3566522-v4-728px-Decorate-a-Small-Bedroom-Step-5Bullet2.jpg","smallWidth":460,"smallHeight":334,"bigWidth":"728","bigHeight":"529","licensing":"<div class=\"mw-parser-output\"><p>License: <a rel=\"nofollow\" class=\"external text\" href=\"https:\/\/creativecommons.org\/licenses\/by-nc-sa\/3.0\/\">Creative Commons<\/a><br>\n<\/p><p><br \/>\n<\/p><\/div>"} In order to avoid having a room that looks too "busy," add one or two pieces that really stand out and draw the eye's attention. This piece can be a colored headboard, an accent wall, a painting, or curtains. That way it will double as a headboard (or serve to frame an existing headboard) and create harmony. The key is to look for unique items that will add character and dimension to your room. Try adding a ruffled bedspread, textured throw pillows, a patterned rug, or woven wood items.

Summary:
Add splashes of colour. Create a focal point. If you decide to paint an accent wall, it will be wise doing it directly behind your bed. Experiment with different patterns, textures, and styles.
