Start small. A colored scarf, bag or pair of shoes against neutrals is an easy first step.
Tonal dressing, with different shades of the same color head to toe, looks polished and is surprisingly easy to pull off.
Pairing colors that sit opposite each other on the color wheel, like blue and orange or green and pink, creates energy. Neighbors, like blue and green, feel calmer.
Hold colors up to your face in daylight. The shades that make your skin look brighter and your eyes clearer are the ones to wear near your face.
Repeat a color twice in one outfit, say in a top and a bag, and the whole look feels intentional.
