I used Gamesworkshop paints, to get the yellow to have a orange tinge i dipped my brush in some red paint and then washed it out in a small cup of water.
This will turn the water red and dilute the red paint, dip you paintbrush in the cup before adding the yellow to you JP this will give the effect of some areas that have a yellow/orange effect.
Looks better than it sounds and has to be seen in the flesh as the camera dose not show the effect very well.
Once i get the MLC armour ill be getting on with a harness and start designing it soon as ive got and idea of how im going it and the materails im going to use ( all from B&Q)
Youll be the first to find out how ive done this for my costume.
