#E00012 Hex Color

Use #e00012 sparingly as an accent color for calls-to-action or alert buttons where you need to draw the eye immediately. Because it is highly saturated, avoid using it for large backgrounds or body text, as it creates visual fatigue quickly.

Pair Setsugekka with neutral tones like charcoal or cool soft whites to ground its intense energy. These pairings create a balanced contrast, allowing the vibrancy of the red to stand out without feeling chaotic or overwhelming in your design layout.
