color theory

60-30-10 Rule

The 60-30-10 rule prevents the two most common palette failures: monotony (everything one color) and chaos (too many competing colors). The dominant 60% sets the mood. The secondary 30% supports and creates contrast. The accent 10% draws attention to the elements that matter most, like CTAs, highlights, and key data points. Interior designers have used this ratio for decades. It works the same way on screens.
