Red Green Blue ~ Colors of Light ~ Sun Flare in Photography
When learning about photography and color theory, it is important to understand RGB (which stands for Red, Green, and Blue). Without getting bogged down in all the technical stuff, you can see how colors mix in this image below. When it comes to light, red and blue mix to make magenta, red and green mix to make yellow, and green and blue mix to make cyan.
As taught to me in art and science classes, without light, energy waves that produce the sensation of color, we would not have color. Our eyes only see a small part of the spectrum of light, with short wavelengths starting as blue to the long wavelengths seen as red. When taking a photograph, it is often hard to “see” this in our pictures. Sun flare sometimes will allow you to see the colors. Rainbows will as well. And since a picture is worth a thousand words, I have two recent shots that may help you better see the RGB.
I would love all of you to share photos in the comment section of rainbows or sun flare where you can see the colors of light separated out into light. If you do not have any, challenge yourself to go out on a sunny day and try for different types of flare. Try partially blocking the sun off a building and try to grab colors of flare. It takes practice and experimentation, but you can get fun, artistic results, and will learn about photography in the process.
In this shot, you can literally see the red, green and blue in the light coming from the sun.
And in this one, you can see the sun flare and lighter rings of color (red and green). Likely, I would have needed a greater angle to see the blue:
