Yes, when we were young, we played with a crayon in school and learned color. What colors look good together, and what colors do not? Who knew that I would play with color again? Not crayon’s but with flashes with gels. We heard the term RGB but what does it mean? Red, Green, and Blue. With these colors, we see all colors. Like your TV or computer is RGB. But what happens when I combine all three? If you said white, you are correct. I saw this setup in the book Studio Anywhere, and I always wanted to do it. In my family room with a white wall, I set up 3 flashes equal in power and in-line with the subject. I placed a filer on each (red, green, and blue). Next, I took the shot and got this.

Remember, RGB equals white. Noted on the subject, but what happens in the background or shadows? You see Red and Green = Yellow, Green and Blue = Cyan, and Red and Blue = Magenta. This is what you see in the background. Now I know what you are saying. Why? Well, maybe a picture of something different? Plus, the understanding color will help your photography and what you can do with flash if needed. Last I wanted to do it, and I did it. Ok, what makes black? Combine the cyan, magenta, and yellow, and you have black. When we print, we print in CMYK and see our TV or Computer Screen in RGB.
