Question: In Preview on OS X 10.9 Mavericks, is it possible to change the color to something other than yellow, green, blue, pink, purple? I know it is possible to highlight in other colors because I did it while using Preview for the first time after upgrading to Mavericks, but now that I've changed I can't seem to change back.

Answer: 
1. Select the underline option
2. Underline text by selecting
3. Right click on underlined text and change it to a highlight color
4. Underline text again by selecting
5. Right click again on underlined text and choose a different color

The new highlighted color will be a mix of the two different colors.  

Sort of like mixing food coloring; for example try mixing two yellows with a pink.

To change the highlight color simply right click a highlighted selection then choose another color
