The jade is base Caliban green, layer up the bigger streaks with Kabalite green until they're visible. Then I mixed in I think Temple Guard blue in with the Kabalite in a couple of different quantities until I felt the smallest lines were bright enough. I also did a bit of stippling.
For comparison this is a Skink Alpha I did a couple years ago when I last painted lizards. I actually couldn't find the old GW video that I followed for the jade so I just found a picture of jade I liked and tried to follow it.
