The pink color ratio refers to the proportion of different shades of pink used in a design or product. It is important in achieving a harmonious and visually appealing color scheme. In design, understanding color ratios and how they affect the perception of space and mood is crucial. The most common ratio is the 60-30-10 rule, where the dominant color is 60% of the space, the secondary color is 30%, and the accent color is 10%. This balance ensures a cohesive and engaging aesthetic.
