Blue is the most common favorite color of people worldwide. It is often associated with the sky, oceans, water, ice, cold, peace, serenity, and at times sadness.
Naturally occurring blue foods are rare which may be why blue is also commonly thought to be an appetite suppressant.
“Feeling blue” “I’ve got the blues.”
“Blue is a power like that of nature in winter, when all germination and growth is hidden in darkness and silence. Blue is always shadowy, and tends in its greatest glory to darkness. It is an intangible nothing, and yet present as the transparent atmosphere. […] Blue beckons our spirit with the vibrations of faith into the infinite distances of spirit.” — Johannes Itten, The Elements of Color, 1970
