Highlight with Purpose
Highlighting is a great way to isolate information in a body of text. However, sometimes you want to segregate that data even further by using different highlight colors. In DEVONthink's Format > Highlight Color menu you''ll find seven available colors to choose. But maybe a few of those colors don't suit your taste, or you have a specific color scheme you use elsewhere.
In Preferences > Colors > Highlighting you can change the color to fit your needs. You can even change the color's name. For example, you may want to highlight arguments in the text in green and conclusions in yellow. Or maybe you just want to give it a name that fits your personality, like Cherry Red instead of Red.
These colors are global to the application. You cannot set highlight or label colors on a per document or database level.
