Final answer:
The use of analogous colors and cool colors in a publication creates a calming and harmonious effect. Analogous colors sit next to each other on the color wheel and create a sense of calm because of their close relation. Cool colors like blues, greens, and purples evoke feelings of relaxation.
Step-by-step explanation:
The color theory that aids in creating a calming and harmonious effect in a publication is largely centred around the use of analogous colors and cool colors. Analogous colors are those that reside next to each other on the color wheel. Incorporating these colors in a publication creates a calming effect because of their close relationship to one another. Similarly, cool colors, which include blues, greens, and purples, generally evoke feelings of calm and relaxation due to their associations with nature and tranquility.
