The main difference between Lavender and Periwinkle is hue — Lavender is a cool off-white, while Periwinkle is a cool purple. Lavender (#E6E6FA) and Periwinkle (#CCCCFF) are similar colors often confused. They differ in brightness, saturation, and undertone, making each better suited for different design contexts.
Four real design scenarios, with the recommended pick based on hue, saturation, and WCAG contrast.
Periwinkle is more saturated (100% HSL vs 67%) so it reads as bolder and more memorable at logo scale, while Lavender can feel washed out when printed small.
Periwinkle hits a 1.54:1 WCAG contrast against white — safer for text-heavy interfaces — where Lavender only reaches 1.23:1 and risks failing AA at small body sizes.
Lavender is a cool-leaning tone that flatters spring/summer collections and warmer skin undertones, while Periwinkle leans cooler and is better suited to autumn/winter layering.
Lavender is the more muted of the two (67% saturation) and sits more calmly on large wall surfaces, while Periwinkle's higher chroma can overwhelm a room when used beyond accent pieces.
Lavender (#E6E6FA) is a very light, moderately saturated off-white with a cool undertone — it feels pale, delicate, gentle and balanced in intensity.
Periwinkle (#CCCCFF) is a very light, vivid purple with a cool undertone — it feels pale, delicate, gentle 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.
