Getting started with colour
Work with what you've gotThere is a lot that can be done without repainting a room. If there is an obvious feature in the room use that as a starting point. If the room is neutral, choose a colour scheme that compliments and brightens. Neutral colours have either a warm or cool background. Use that to decide wether you go warm or cool in your colour approach.
Use art as a focal point. When I'm styling, my job is to bring a room alive without painting any walls. I do that by choosing a piece of art that includes the colours I want the room scheme to be. This might be monochromatic, or super colourful.
Experiment Be daring. Break the rules. Change out the colours of a room with soft furnishings. Live with it for a while and see how you feel. I change the scheme of my bedroom each season. Colours effect our mood. In summer I enjoy bright and light. In autumn I muddy it up a bit. And come winter the tones are dark and cosy.
Colours don't have to match There are infinite colour combinations. My approach is to create an overall room by using all the elements (linens/art/objects/furniture) to make up the scheme. Other than pillowcases on beds, generally I never have more than one of anything - ie cushions will be different, throw will be different from the duvet. Rug will be different from the carpet. But overall in the room there will be multiple things in the same colour. If you can master this approach your rooms will have depth and interest.
