A '10 color color scheme' refers to a design palette that includes ten different colors. This type of scheme is often used in graphic design, web design, and interior design to ensure a balanced and visually appealing color combination. Designers may use various methods to select these colors, such as the complementary color scheme, analogous color scheme, or monochromatic color scheme. It is important to consider the contrast and harmony between the colors to create an effective and cohesive design.
