Vermilion (#E73121) is a vibrant red that commands attention with its fiery intensity. This striking color blends red's passion with orange's energy, creating a hue that symbolizes power, excitement, and urgency.

Historically rooted in ancient Chinese ceremonial arts, vermilion was originally made from cinnabar mineral, making it both precious and dangerous to produce. Today's synthetic versions preserve the color's dramatic impact without the historical toxicity.

In design, vermilion excels at creating focal points and driving action. Use it strategically for call-to-action buttons, notifications, or highlighting important elements. Its boldness makes it perfect for gaming, entertainment, and fitness applications where energy matters.

For stunning combinations, pair vermilion with jet black for dramatic contrast, yellow-orange for warmth, or copper for earthy richness. Consider complementary colors like scarlet and cinnabar for related alternatives.

Remember: vermilion's stimulating nature can overwhelm if overused. Apply it sparingly to maintain its powerful impact and avoid visual fatigue in your designs.
