I have had multiple colors in the past, red, green orange, purple and a few shades of yellow. High light wipes most of it out except the light purple and some of the orange. I have some really cool looking orange at the moment but directly under the 250 watt 10K XDE no coraline will grow.
In a group buy a few years ago I got some Eva rock from Phishy and it was covered in the most wonderful coraline of many different colors. Most of that is now gone. :-(
