#FF4040
X11 color
Brown 1 (#FF4040) is a striking paradox in the X11 naming system—it appears as a vivid, fully saturated coral red, not what most people would call brown. This naming reflects X11's mathematical approach to color variants rather than perceptual naming. In practice, it functions as a bright red-orange accent color suitable for alerts and vibrant designs.

Tâm lý màu sắc
Vivid pinks project confidence, playfulness, and bold self-expression. They challenge traditional associations, carrying both the warmth of red and the creativity of violet. Hot pink in particular signals rebellion against conventions and unapologetic individuality.
Design Usage
Medium pink is effective for fashion brands, social media platforms, and marketing campaigns targeting Gen Z audiences. It makes impactful gradient elements when blended with purple or orange. Use it for accent buttons and promotional banners where energy and excitement should override corporate formality.
