You need to have inspiration on choosing a decoration theme first, instead of deciding the color immediately. Pinterest is a great place to start when deciding on paint colors.
For example, a contemporary theme would tend toward subtle, neutral colors, while an Asian theme would lead you to choose stronger colors such as reds, golds and greens with perhaps black accents.
Match Your Paint Colors with Furniture and Fabrics
Use a large colored card paper against your sofa, bed or other items that will be in the room to see if goes.
A good way to coordinate with fabrics is to select colors that are visible in the fabric but not the dominant color. You don’t necessarily want to match, but you do want the undertones to go nicely.
Colors will look different in different types of light.
For example, fluorescent light provide light with a slight green tinge while incandescent and halogen lights will produce a yellowish tinge that tends to dull cool colors.
rooms with lots of sunlight should be painted in lighter tones so they don’t feel uncomfortably warm.
