Reds, yellows and oranges are considered to be warm colors, while blues, greens and violets are considered to be cool. Warm colors condense a room making it feel energized, intimate and cozy while cool colors expand a room making it feel open and calming.
You can combine both colors in your home cool or warm, to complement or contrast each other.
A warm color placed next to a cool color will look warmer and make the cool color look cooler.
More muted tones tend to work better than brighter hues with strong color intensities.
Try to keep colors similar in big open spaces to maintain a visual harmony. Separate rooms can maintain a more distinct color identity but still need to have a sense of color cohesiveness.
