Winter white is a soft white, a gentle, almost creamy white. It is the white of snow glowing in the sunshine, a warm and friendly white. You can wear winter white, you can decorate with winter white, you can get winter white flowers, and (most of the time) you see winter white when you look out of the window in our latitudes.
Winter here in the northeast with its whites, dirty whites, browns and grays expresses an absence of vibrant colors. Not only is winter a time of slowing down in general (see a previous post on hibernation), it also lets the eyes rest from the vivid colors we experience the rest of the year. Winter is a time to reboot your color sense, putting it back into neutral gear.
