And you can see the brightness values changing on the info panel. If I move to the fifth concentric ring and from that point to the outside of the circle, I'm moving towards a darker shade of the color. It may be a few digits out, but it's more or less the same. Whether I'm close to the edge or close to the center. Change the color readout to HSB color and the point I want to make is that no matter what piece of the slice that I'm in, the hue angle will be the same. I'll now open the info panel, which if you don't see it you'll find under the window menu. Click okay, that takes me back to my layer style options, and here I want to change the blend mode from normal to hard light. If I come to my cog and then down to special effects, append my special effects gradients and amongst those is one called gray value stripes, that's the one that I want. Now I'll click on my gradient bar and I need a specific type of gradient. I want to make sure that the style of gradient I'm using is radial and I want it to be reversed, so that we go from light at the center, to dark at the outside of the circle. From my FX dropdown, I will choose gradient overlay. And I'm now going to apply a gradient overlay, which will give us our tints and our shades of our 12 colors. As I did before, I'm going to press cmd, or ctrl, E to merge that layer with the layer beneath. So we have our primary, our secondary and tertiary colors and we have red at zero degrees and opposite that on the circle, cyan at 180 degrees. Rather than change the layer blending mode, this time I'm going to change the opacity from 100 to 50% and we now have an interaction of those two layers showing our tertiary colors. I'll press cmd, or ctrl, T to bring up my transformation rectangle, come to my angle field and type in 30 and press enter or return. This time, I want to rotate the copy through 30 degrees. And now, I'm going to duplicate the result by once again, pressing cmd, or ctrl, J. I want to merge these two layers together by pressing cmd, E. Now because we're working with the additive color model, RGB, if I change my layer blend mode to lighten, then we now have our secondary colors: cyan, magenta and yellow. Press cmd, or ctrl, T to bring up free transform and then come to the angle field in your tool options and I'm going to type in 6D and press enter, or return. I now want to rotate this top copy of the circle through 60 degrees. To begin, I'll come to layer one and duplicate that layer by pressing cmd, or ctrl, J. I also have a vector Smart Object layer, indicating the angle of the color around the circle. I'll begin with this circle divided into the three additive primaries: red, green and blue. I'll use layer blend modes to create the secondary and tertiary colors and a gradient to create tints and shades of the colors. It's an informative exercise to create a color wheel in Photoshop and that's what I'll do in this movie. The color wheel is a simple, yet powerful tool for understanding how color works and how colors relate to each other.
