Forbidden Colors

Forbidden Colors



Have you ever heard the saying “If the human brain were so simple that we could understand it, we would be so simple that we couldn’t?” (said by Emerson M. Pugh) I can’t stress the amount of truth found in that statement. The human brain is notoriously difficult to understand, despite our spending billions of dollars for the best minds to try to comprehend why it does some of the things it does.

In this instance, what exactly “is” color and why are we unable to perceive certain hues from an object that’s simultaneously emitting wavelengths that could be interpreted as blue -and- yellow or red -and- green in ordinary viewing conditions? That’s what we refer to as “forbidden colors” (or impossible colors, whatever floats your boat), a hue that’s a combination of various intensities of various frequencies of visible light and actually, it’s possible to see these “forbidden” colors. Now, when I say this, I’m not referring to the colors you get when you mix certain paints.

When this happens, you’re merely mixing a primary and secondary color together to get an intermediate color. Instead, you can train your brain to get around the “opponent channels” that are responsible for seeing and processing visible light, which in turn, processes visual information efficiently while limiting the range of visible colors on the spectrum. This finding suggests that color opponency, which is responsible for cancelling out certain hues (red versus green, blue versus yellow and black versus white), can be disabled, thus allowing the human visual system to interpret wavelengths of color that aren’t accessible to the naked eye.

Here’s how you can train yourself to see ‘forbidden’ colors:
