In some languages, there are no separate words for blue and green; linguists call these colors simply, “grue.” Yet, in English, we have subcategories for every imaginable blue hue: sky-blue, azure, pale blue, navy, periwinkle, turquoise, baby blue, midnight blue, ultramarine, cobalt, grey-blue, true blue, and many more. Scientists tell us blue light will reset body rhythms for sounder sleep and higher alertness. Blue is sky and water; eyes and stones; slumber and spring — with summer right behind.
