Don’t get me wrong, there are several books out there with good intentions, and every once in a while I will read something that really inspires me or sends me in a new direction. But I would really like to see some advances in the material being presented. I’m often found scouring the web for tutorials that break out of the mold and teach you something truly unique, useful, and intriguing. I believe it is with those three things that a really good writer/teacher is found.
That being said, I hope this tutorial will give you a bit of all three. It’s not anything earth-shattering, but it’s something that I’ve yet to see demonstrated anywhere else. In this tutorial I’m going to take a step back and explore a little known functionality of Photoshop, and that is its ability to create color schemes or color harmonies.
What do I mean by this? Well, let’s say you have a website or a print project, and you have explored your layout. You know what you want to present, and you may even have all the elements that you want to put together ready to go. But what you don’t have is a color scheme. A few matching colors that look good together. Colors that will pull out the presentation and work together to produce a good design. I used to struggle to find good color combinations. But after a while I started thinking that there may be a better way to design. There may be a quick solution for finding colors that look good together.
So I started reading some books, and talking to other designers, and what I found inspired me to try to work Photoshop into providing me with color schemes. Adobe has dabbled with this concept before: in an old program called ImageStyler, there was a color scheme palette which produced a variety of colors (6 in total I believe) that were based on a single color which the user chose. When ImageStyler went the way of the dinosaur, LiveMotion took over and adopted this Color Scheme palette. I’m not sure if it is still available in this program or not, but I can tell you there are several color schemer programs and applets out there that will do all the work for you and charge you a fee for your lack of knowledge.
Understanding Color Harmonies
Traditionally, there are a few basic color harmonies. This is not an exhaustive list, however, the most common are as follows:
- Complementary: This scheme uses two colors which are directly opposed on the color wheel (for example: Red and Cyan)
Split Complementary: This scheme uses 3 colors. One color and two other colors that are directly adjacent to its complement on the color wheel (for example: Red, Cyan-Green, and Cyan-Blue)
Triad: This color scheme uses 3 colors that are equally spaced out on the color wheel (for example: Red, Blue, and Green)
Analogous: This scheme uses three colors, one that is in the center, and the two colors adjacent to it on the color wheel (for example: Red, Red-Orange, and Red-Violet).
Monochromatic: This color scheme uses colors from the same Hue on the color wheel, but with varying saturation and/or lightness (for example: different shades or tints of red).
Translating Color Harmonies in Photoshop
In order to do that, we must first translate our Color Wheel into the Hue slider on the Hue/Saturation dialog. Here is how it’s done:
- The Color Wheel (which is circular) is translated into the Hue/Saturation dialog (which is linear). This is why +180 and –180 on the Hue slider in the dialog will give you the same color. Just as 0 and 360 on the color wheel give you the same color. Just keep in the back of your mind that adjusting the linear Hue slider actually moves the colors around the color wheel in a circle.
- The Hue/Saturation dialog uses relative color shifting. This means that whatever color you initially select, the numbers in the color wheel shift relative to that color. For example: the above color wheel is valid only if Red is your starting color. If you select Blue as your starting color–located at position "–120", all the numbers will shift so that Blue becomes the new "0/360" position (all the other numbers above will shift accordingly). Note that it is not the colors that change, but the numbers that calculate the colors. The color wheel itself stays constant. By contrast, if the Hue/Saturation dialog used "Absolute" color shifting, then the color Red would always be located at position "0/360".
Here are the Color Scheme locations in relation to the sliders on the Hue/Saturation dialog. Note that all schemes except Monochromatic use the Hue slider to find the appropriate colors. Indeed this is really the only slider you need to adjust for most of the color schemes.

Automating Color Schemes Using an Action
Step 1First, create a new image. 400x400 pixels should give us enough room to work comfortably.
Step 2Next, fill the layer with 50% gray. This is good because we can view our colors against a neutral background. When that is done, create a new layer, and make a simple square selection on the new layer. We are going to place each of our colors on a different layer so they are easy to manipulate.
Step 3Next, fill the square with any color. This will be the base, or original color that will be used to base all other colors within the color scheme. Be sure to keep the selection active during this process.
Step 4Next, duplicate the color layer. Move the square below the original color. This is going to be our complement color. On the duplicate layer, click Ctrl/Command+I to get the inverse of the original color. If you like, you can label this layer "Complementary". In our example below, since Cyan is the complement to red, the square is filled with Cyan.
Step 5Next, create 2additional layers and move them below the two color squares. These will be our Triads. Be sure they are the same color as the original square (red in this example).
Step 6When you are done, group these layers with their respective color squares by holding the Alt/Command key and hovering your mouse over the line between the adjustment layer and the layer below. When you see the link cursor, click with your mouse. This will group the adjustment layer with the layer below it. You can merge each of these grouped layers down if you would like to save space and reduce the number of layers in your document.
Step 7We’ll work on the Split Complements in the same way. Split Complements are separated by 150 degrees on the color wheel in either direction, so perform the same operation as you did with the split complements, only this time change the Hue in the Hue/Saturation dialog by negative 150 and positive 150 degrees in either direction. You will end up with the following diagram:
Step 8Next, let’s try our hand at Monochromatic colors. Monochromatic colors simply mean the same hue, but a variation in the tint, shade, or saturation of the color. These are perhaps the easiest colors to recreate, the only difference is that instead of changing the Hue, you will need to change the saturation. Note that you can also change the lightness slider as well, but I would start off slow and change the saturation in any increment level you like.
Step 9Lastly, follow the same steps to produce Analogous colors by increasing or decreasing your Hue slider to +30 and –30 respectively. In the action I created, I also included two other analogous colors with +60/-60 Hue shifts just to make it a little more interesting.
Here are the results of the action when it was run using red as the original color. This automatically creates the Complementary, Split Complementaries, Triads, 5 Monochromatic colors, and 4 Analogous colors of the original color. Depending what color you initially select in your foreground, the results will be different each time. Once the action is run, you can sample from any of the squares to place the color in your foreground, or save the colors in your Swatches palette.
I hope you find this tutorial useful. Feel free to download the action here. And try creating your own color combinations based on the hue/saturation dialog, or even try applying the same methods to the channel mixer dialog to come up with some interesting results. Until next time, good luck with all your Photoshop projects.
