Painting a Glow EffectCompiled & Edited by Support to include information by Shas'Ui Faol & Shas'O Eiglepulper The following are methods for applying glow effect to your Tau craft or weapons. Information supplied here is by avid hobbyists like yourself in an effort to encourage the growth of painting skills on Advanced Tau Tactica.
The Glow effect is generally referring to the splash over colour a light source projects over nearby objects and surfaces. However, whilst in some cases it can become remarkably involved and lavish exercise in brush skills, Tau hobbyists usually require something quick and effective for their units of the line. Reserving the special variations for their most favoured pieces.
The following are straightforward guides to quite remarkable results :
Shas'Ui Faol's Method (For Blue Glow Effect):The paints I use in order form dark to light. All are blue save the final color which is skull white.
Midnight Blue
Regal Blue
Enchanted Blue
Ice Blue
Skull White
Start of by painting the engine vanes midnight blue
Next move in just a bit and paint Regal Blue making sure to leave some of the midnight blue showing
Next follow up with Enchanted blue moving in just a bit leaving some regal blue showing
After that use Enchanted Blue in the same way moving in just a bit leaving the other blues showing
Finally paint a small line of Ice Blue
Then a dot of skull white in the center
Very simple, much like layering. More advanced blending could be performed by making your darkest blue lighter through adding lighter blues, but this is straightforward and it looks good.
Shas'O Eiglepulper's Additional Method (For Blue Glow Effect):I then used a 1:1 water/wash ratio of Asurmen Blue Citadel Wash over the painted sections, followed by a 0.5:1 water/wash of Vallejo Transparent Blue to get that sapphire colour going. Here's a close-up of the engine vanes. Ignore the mould lines, they aren't really there - honest.

The same theory was used to give an impression of a plasma reactor in the engine pod itself when looking through the exhaust manifold. Unfortunately this picture was taken indoors and so the lighting isn't as good and the effects are lessened because of this:

When seen up close the layering on the engine vanes is painfully obvious, but when seen from further back the effect is rather different.
