Good color coordination of adjacent colors

Quick answer：

Adjacent colors are colors that are next to each other on the color wheel, such as red and red-violet or blue and blue-green. Good color coordination of adjacent colors involves selecting tones that harmonize well together, often with one color being dominant and the other providing a complementary or contrasting touch. This technique is commonly used in fashion, interior design, and graphic design to create aesthetically pleasing and cohesive visuals.
