The main difference between Periwinkle and Cornflower is hue — Periwinkle is a cool purple, while Cornflower is a cool blue. Periwinkle and Cornflower are often confused but differ in brightness, saturation, and undertone. Periwinkle (#CCCCFF) and Cornflower (#6495ED) each have distinct characteristics and best uses.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Periwinkle is more saturated (100% HSL vs 79%) so it reads as bolder and more memorable at logo scale, while Cornflower can feel washed out when printed small.
Cornflower hits a 2.97:1 WCAG contrast against white — safer for text-heavy interfaces — where Periwinkle only reaches 1.54:1 and risks failing AA at small body sizes.
Periwinkle is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Cornflower leans cooler and is better suited to autumn/winter layering.
Cornflower is the more muted of the two (79% saturation) and sits more calmly on large wall surfaces, while Periwinkle's higher chroma can overwhelm a room when used beyond accent pieces.
Periwinkle (#CCCCFF) is a very light, vivid purple with a cool undertone — it feels pale, delicate, gentle and bright, energetic, eye-catching.
Cornflower (#6495ED) is a light, vivid blue with a cool undertone — it feels airy, soft, approachable and bright, energetic, eye-catching.
Text legibility depends on the contrast ratio between foreground and background. WCAG 2.1 AA requires at least 4.5:1 for normal text and 3:1 for large text; AAA requires 7:1. Use these numbers to choose accessible combinations for your design.
