Take all the color out of your mind, strip your consciousness of preconceived thoughts as they pertain to sunsets and rainbows and black birds and blue jays and let the shape of things before you shape your appreciation for them. One needn't have color to know that color exists since contrast and contour, shadow and texture have a palette all their own.
Go on, look at the world in black and white at times and watch how it colors your appreciation for it. . .
