Once you have chosen a color palette for your course, you might want to make use of it in PowerPoint to create some graphics or make a presentation for your students.
One way to create a color palette is to use the color wheel. Adobe has an interactive color wheel at color.adobe.com. You can use the sliders to find a particular color, and then select a color rule to see its complement on the color wheel or the two colors that go along with it to form a triad. You can also generate an analogous, monochromatic, or compound pattern based on the color. (Check out the color theory reference chart to see how those color relationships are formed.)
When you find a great color you want to be able to replicate it. Two common ways that designers talk about color are RGB values and Hex values.
RGB values look like this: R: 186 G: 47 B: 39. The red, green, and blue values can be any number from 0 to 225.
Hex values look like this: #BA2F27. Each of the 6 digits in the number can be a number from 0 to 9 or a letter from A to F.
Some programs will ask for the RGB value, others will ask for the Hex value. But as long as you know one of the two, it’s easy to convert it to the other value.
If you know the RGB value and need the Hex value, use the converter at http://www.rgbtohex.net.

If you are trying to find a color palette for your course, check out Design Seeds. This blog is constantly updated with new color palettes. Each post shows you the palette and also gives you the hex codes for each color in the palette.
I like to browse the recent posts whenever I need inspiration. But the search by color option is great for the times when I have a specific color in mind and want to find complementary colors to go along with it.
