Color values: Hex FF66AA; RGB 255, 102, 170; CMYK approximately 0, 60, 33, 0; and HSL approximately 333°, 100%, 70%. The hue around 333 degrees places it in the pink-magenta spectrum; saturation is high, and lightness is high as well, resulting in a vivid pastel-like pink.

Appearance and usage: FF66AA appears as a bright pink with purple undertones. It is used for accents, highlights, and call-to-action elements where high visibility is desired. It is often paired with dark text or muted neutrals to maintain legibility.

Accessibility considerations: On white or light backgrounds the color produces a contrast ratio around 2.7:1, which fails WCAG for body text. On dark backgrounds the contrast increases (roughly 7.5:1), making it more suitable for emphasis. Designers often adjust saturation or value for readability.
