Mark Text with Colour

DEVONthink allows you to set the background colour of selected text. Simply select the piece of text you want to highlight and choose "Format > Highlight". This is very convenient for highlighting interesting paragraphs in documents clipped from another data source, e.g. a web page. Also, the colour panel features a checkbox which allows you to set the background instead of the ink colour.

Note: Text highlighting only works with rich text, not with plain text documents.
