#ffff00 - Yellow color

A brilliant, pure yellow that reads as vivid sunlight or caution signage. It’s high-energy and highly visible, with a warm, cheerful quality that evokes optimism, alertness, and creativity. In digital color models it’s produced by combining full-intensity red and green light with no blue, yielding maximum luminance and clear chroma. Designers use this yellow for attention-grabbing accents, warning icons, and playful branding; however, use it sparingly to avoid visual fatigue or contrast issues.
