khaki 3

Khaki 3 (#CDC673) is a medium warm olive-yellow from the X11 khaki series, beginning to take on the earthy, grain-colored quality associated with military khaki. It suggests dry savannah grass, washed canvas, and natural muslin fabric. This is the variant that most closely corresponds to the classic khaki concept in textile design.

Pure yellow is the most luminous color in the spectrum, instantly associated with sunshine, optimism, and alertness. It stimulates the nervous system and enhances concentration, which is why it appears on school buses and warning signs. Yellow demands attention faster than any other color.

Medium yellow is powerful for attention badges, star ratings, and highlight accents in otherwise neutral interfaces. It is one of the hardest colors to use as a primary brand color because of contrast limitations against white. Dark text on yellow achieves strong readability, making it effective for caution banners.
