Psychology
Yellow is the most luminous color the eye perceives, making it both attention-grabbing and tiring at high saturation. Cognitively it's linked to clarity, optimism, and idea-generation.
Meaning
Sunlight, gold, caution, and intellect all live here. In some Asian traditions yellow signifies imperial power; in Western coding it's the universal hazard color.
Applications
Excellent for highlights, badges, and small accents against dark backgrounds. Soft buttery yellows work well as page backgrounds; high-chroma yellow needs dark ink for legibility.
