Color blues and greys for living room. Color yellow and grey for bathroom. Color peach and grey for bedroom. Get a canvas or cardboard and some fake flowers then glue the flowers on it and spray paint it with colors to add some color to your room.
Simply fill a small jar with water and then cut open a glow stick and pour it in! I used some kitchen shears to cut the top off of the glow stick. Gently swish around the water (but do NOT shake) and you're set!
