The real reason though I've put up this tutorial is I couldn't easily find where to do this particular scheme despite it being a very useful one that can work on Lizards, Tyranids or Imperial Guard. So without further adieu:
Paints you'll need:
Black Spray Paint
These are a mix of different generations of Citadel Paints and you might have to use different ones. You can find a conversion chart at:
The second step is to thickly drybrush the model Kommando Khaki followed by a light drybrush of Bleached Bone (depending on how light you want the skin to be.) I don't bother doing the scales or shield at this point.
I then wash the skin with Gryphonne Sepia, ensuring I use enough to get good coverage of the model and bring out the definition of the skin. Areas to focus on are the crests and the folds in their torso by where their ribs are (I assume skinks have ribs). Be careful to only lightly wash near the scales as since we're speed painting we don't want wet ink there for the next step.
It's coming together now and we paint the Mechrite Red on first the shield (to give any sepia ink time to dry) and then on the scales. There's no requirement to be exact with the scales and I just slap the paint on.
While the Mechrite Red is drying we will pick out the details. Paint the shaft of the javelin Chaos Black, the tip Chainmail and the mount for it Dwarven Bronze. I also paint any jewellery Dwarven Bronze at this stage. To paint the eyes I paint the eyeball bubonic brown and then paint a thin line in the centre which gives the impression of a reptilian eye. The tongue gets painted Blood Red and any feathers are painted Scorpion Green.
The final step is a quick wash of Badab Black on the shield and scales. Really you can use any wash you want but I like the dark contrast Badab Black provides. Voila! your model is done. I hope this quick tutorial has been of some value and I think the colour scheme is a universally effective one that can be used for many armies and as such a good one to have in the toolbox. Cheers and thanks for reading.
