Periwinkle (#CCCCFF) is a delicate pale indigo that beautifully bridges the gap between blue and purple. Named after the charming periwinkle flower, this soft hue brings a sense of serenity and calmness to any design.

With RGB values of 204, 204, 255, periwinkle creates an anchoring effect when paired with vibrant colors like pastel orange or lime green. It also harmonizes perfectly with fellow pastels such as lavender and light blue for dreamy, cohesive palettes.

Designers love periwinkle for its versatility – it reduces eye strain when used as a background color, helps important elements pop without overwhelming users, and creates that coveted calming atmosphere perfect for wellness and meditation apps. The color psychology behind periwinkle combines blue's trustworthiness with purple's creativity, making it ideal for projects that need to feel both professional and approachable.

Interestingly, periwinkle was first recorded as a color name in English in 1922 and added to Crayola's palette in 1949. Today, it's experiencing a renaissance in modern design, often paired with cornflower blue or pastel yellow for fresh, contemporary looks that never go out of style.
