● For Illustrations and Photos
A high complexity score does not necessarily mean "NG" (not good). High complexity often conveys a "lively" and dynamic impression, while low complexity conveys a "calm" and static impression.
The ideal level of complexity depends on the product or item. It is recommended to compare the complexity scores of competitors' designs, old designs, and new designs to make a relative judgment.
● For Text
In text-centric designs such as PowerPoint slides or websites, simpler designs tend to improve readability and processing fluency.
As a guideline, complexity below 50% enhances readability.
