寒色の効果

Cool colors (blue, green, violet) have been shown to lower blood pressure, reduce heart rate, and promote a sense of calm and focus. Office environments and productivity tools favor blue tones because they support concentration without causing drowsiness. Cool colors also make spaces feel larger and more open, which is why they are popular in small-room interior design. In healthcare, blue and green dominate because they convey trust, cleanliness, and competence. The calming effect of cool colors makes them ideal for long-form reading experiences, meditation apps, and financial dashboards where trust and stability are paramount.
