I have tried many PDF readers (evince, okular, FoxitReader, etc.) and found evince the most minimal and practical one. Yet, with version 6 of Zotero, came a built-in PDF viewer with some features. Of them, one greatly changed my experience in reading pdfs, and that's the ease of color-coded highlighting: With no extra click, a little pop-up with a few colors will show up once you select a piece of text in Zotero's PDF viewer. If you further select one of the colors, the text will be highlighted with the corresponding color (very similar to the experiences you may have with the Textmarker plugin on the web).
I like to have that feature off Zotero as well. Do you know any viewer that has such a feature or can be configured for that? Those that I've tried, indeed, all let you highlight with several colors, but after tons of extra clicks.
Thanks!
Note: You may be wondering why I don't import my PDFs to Zotero and read everything there. This I don't do because I don't what my files to clutter with the library that I keep in Zotero.
