#ff0000 - Red color

An intense, pure primary red—fully saturated and vividly warm. It radiates energy, urgency, and passion, often evoking love, heat, and danger. In design it commands attention, serving as a powerful accent for warnings, calls to action, and branding that seeks boldness. Against neutrals it pops; paired with complementary green it creates high contrast. Used sparingly it excites and energizes; in large fields it can feel aggressive or overwhelming, so balance and context are important.
