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.
