Periwinkle is a light, milky shade of blue, similar to cornflower blue, but with a tinge of lavender. The color is named for the periwinkle flower.
In the yard, periwinkle plants provide hardy, widespread light-purplish-blue coverage that is especially thick in shady areas. Inside the home, the color periwinkle is light enough to be considered neutral in the blue family, or the purple hues can be brought out with lighting and brighter purple accessories. In fashion, periwinkle is often used as a feminine fashion color, but some men's dress shirts are created with fabric in this soft-looking color, and then embellished with darker accent pieces.
