Thanks guys, really appreciate it. I have kind of made a rod for my own back though because it takes an age to finish a squad but I do like the look it gives.
For those interested it takes between 3 to 5 colours depending on whether I want to make them seem more or less powerful/fed/powered up (whatever you want to call it).
The colours are, scab red, blood red, blazing orange, golden yellow & sunburst yellow. You can see the parts of the raider that don't have all 5 colours. I can vary how much each model glows by leaving out 1 or 2 of the colours.
Glad you like them, more to come between 2 kids a wife and a demanding job lol
