The only thing worse than being blind
is having sight but no vision.
~ Helen Keller
Imagine the Crayola world of a child. Regardless of age or prowess, and with little need to be adroit they can conjure a world of squiggles and stickmen to rival Picasso; squiggles that translate to a castle or space flight or a talking dinosaur; squiggles that adorn a refrigerator as if the Louvre.
From a platform of red, green and blue every other color in the spectrum is born. Those three and their offspring are the humble servants of a child that needs little more to bring life to their own visions.
Be it one color or hundreds, every single hue derives from the trichromatic of red, blue and green. I'd find that hard to believe were it not for the fact that I've held in my own hands a paint color spectrum ~ you know them, the sort we'd find at Home Depot and that are used to figure out what color to paint a wall, or which shade matches an already existing color.
The trichromatic principle is a fact in Crayola's world; the one seen with the eye. But it's also true in the spiritual realm, seen only with the heart. Think about it ... From faith, hope & love come every good and noble feature of the inner man. Mix various doses of any or all of them to come up with a spectrum of color that includes such hues as patience, or forgiveness, or self-control.
As a child, once I learned there were far more Crayon shades than the 24 to which I'd been limited, I was not happy until I had a box of 120 for my very own. I'm working on that still, trading the trichromatic world of Crayons for the equally trichromatic world of the spirit; and wondering just how many new shades of faith, hope & love are even possible. I want them all! Because I know those three and their offspring are the humble servants of a child that needs little more to bring life to their own visions.
Vision is the art of seeing
what is invisible to others.
~ Johnathan Swift
Primary colors are sets of colors that can be combined to make a useful range of colors. For human applications, three primary colors are usually used since human color vision is trichromatic. And the three colors that fall within each of the human cone cell sensitivity range are red, green and blue.
