Color Codes
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 know the Hex value and need the RGB value, use the converter at http://www.rgbtohex.net/hextorgb/.
If you need other color values, https://www.colorbook.io allows you to convert hex into RGB, CMYK, and HSL values. It also shows you tints (lighter) and shades (darker) of the color.
Color Palettes
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.
The recent posts are fun to browse when you need inspiration. But the search by color option is great for the times when you have a specific color in mind and want to find complementary colors to go along with it.
Color Palettes in PowerPoint
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.
This website shows you how to customize the color scheme in PowerPoint.
