brown 1

#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.
