A Terminator and a spare Rhino side hull were used for this experiment. There were several goals. One of those was to use as much GW paint as possible, and the other was to keep the the mix of colors to a minimum.
Sons of Orar have white as part of their heraldry. Rather than use full on white, the area is based with fortress grey, and then mostly covered with Ulthuan Grey. A touch of white is used around the edges. It is important to use as little white as possible. White will be used during paint chipping, so it needs to contrast with the grey beneath it. On shoulder pads, whit is only used a the extreme top of the pad. The majority of the pad being left a grayish color.
The main body of the rhino was painted with only two colors. The black basecoat, and mephiston red. The color modulation was achieved using a diluted mephiston red mixture in an air brush. Anywhere two panels came together, more coats of mephiston red went on.
The bottom sides of the smoke stacks were masked off so a gradient could be added.
The gradient is on the right.
With only two panels of the rhino hull completed, the benefits of modulation can already be shown.
Finished color modulation. Wild Rider red was used to highlight rivets. I recommend using this on faces, and front panels of tanks. As the extreme highlight it should be kept minimal. The next step is a gloss coat to protect the paint from oils. Behold the ugliness which is gloss.
A satin coat was sprayed on to dull down the gloss. Vallejo has a blueish tint to their dull and satin coats. I will not use them again for future Sons of Orar, as it interferes with the color too much.
Steel Legion drab was sprayed to add dust to the lower area of the hull. Pigments will be used as well, but I like the tinting the paint does to the the white door and the lower hull.
