Yellow

Yellow is the color of happiness and optimism. It is the most visible color in daylight, making it attention-grabbing and energizing. In Western culture, yellow symbolizes joy, intellect, and caution. In Eastern cultures, yellow is a sacred and imperial color — in China, yellow was reserved for the emperor. Yellow stimulates mental activity and encourages communication. Too much yellow can cause anxiety and visual fatigue.

Yellow is the most attention-grabbing color — used for school buses, taxi cabs, and warning signs. In branding, yellow conveys optimism and youthfulness (McDonald's, Snapchat, IKEA). Yellow is difficult to use in large amounts — it can overwhelm and cause visual fatigue. Use yellow as an accent color against dark backgrounds for maximum impact. Yellow pairs well with black for high contrast and visibility, with blue for a sunny, friendly palette, or with gray for sophistication.

Yellow is one of the oldest colors used in art. Yellow ochre was used in prehistoric cave paintings over 17,000 years ago. In ancient Egypt, yellow was associated with gold and the sun — the skin of gods was often painted yellow. In medieval Europe, yellow had negative associations — it was the color of Judas's robe and was used to mark Jews with yellow badges. In China, yellow was the imperial color — only the emperor could wear yellow. The word 'yellow' comes from the Old English 'geolu', sharing Indo-European roots with 'gold' and 'yellow'.
