Color in all things – visible and invisible

As a beam of light passes through the prism it is bent and changes direction. Different colors of light have different wavelengths, and the angle at which the light is bent depends on the wavelength. If a beam of white light–which contains all the wavelengths of visible light–passes through a prism, it spreads out to form a band of colors called a spectrum.

White light is light that appears to be white or have no color, such as the light from the sun, because it contains all wavelengths or colors of visible light, which combine to make white light.

 

absorbsWhite light, “not there” from what absorbs: a way of describing the primary colors–red, green and blue–by referring to the colors other than themselves (“not there“) that they absorb (take in without reflecting), that is cyan, magenta and yellow. White light can be understood as a combination of red, green and blue light. When white light hits an object, the object reflects its own color and absorbs all other colors that is, it takes in without reflecting the colors that are not it). We perceive the reflected light as the color of the object. For example, the color red reflects red light and absorbs green and blue, which together make cyan. In other words, the color red absorbs cyan from white light.

This is what I’ve learned from studying your spectrum poem. I am grateful for this knowledge. I made the graphics in Photoshop. The thing that amazes me the most is that there is all color in all things but the ones we don’t see in the objects around us are absorbed. I just see it as a miracle even though I know this is science. It is still poetry to me. I am going to do a bit more study on “Outside the Lines“.

    Many things that we do not see are what ultimately sustain us . . . for example, oxygen.
