Color Psychology

Color Temperature

This warm-toned color (hue 4°) triggers psychological responses associated with energy, comfort, and action. Warm colors appear to advance towards the viewer, making elements feel closer and more prominent.

Visual Weight

At 6% lightness, this color carries substantial visual weight. Dark colors add perceived importance and gravity to elements. Research shows dark elements are perceived as 10-30% heavier.
