Some things to consider when choosing paint colors include lighting, mood of the room, hue, paint finishes and ease in manipulation of the color choice. Color choices can have significant psychological effects, according to HGTV.
It is important to pay attention to the lighting of the room to be painted because the lighting affects the color's appearance. Natural light gives the truest representation of color, while incandescent light highlights warmer, more yellow tones, and fluorescent light projects cooler blue tones.
Mood of the room is also important. Soft, cool colors may be a better option to create a more relaxing mood in a bedroom. Choosing a wider color palette for a children's play room can make the room seem fun and exciting.
