The colors I used for the molten effect were:
- GW Khorne Red
- P3 Ember Orange
- P3 Cygnus Yellow
- P3 Menoth White Highlight
- GW Ceramite White
Since the flame/smoke is coming off of the top end, I didn't really have any say in where the hottest point was going to be. Using the above colors and a wet palette, I used wet-blending* for a smooth transition with the colors, with the hot end getting the white and the cooler bottom being the red. The fire was painted with the same idea, so it was basically reverse highlighting (raised areas the darkest colors) with some black added into the mix.
I think I used too much red on the metal, though, as molten metal typically "glows" and remains mostly orange at the darkest. I highlighted the sides with a very dark red (Khorne Red mixed with black, just used the same mixture as the smoke).
*My wet-blending technique here was more of a mix between wet-blending and two-brush blending. Using the molten rune as an example, I painted red on the bottom, Cygnus Yellow in the center, and Ceramite White at the top. Like;
Red - Cygnus Yellow - Ceramite
Then I'd apply the transition color of Ember Orange between the red and yellow, and a mix of yellow and ceramite between those, like;
Red - Ember Orange - Cygnus Yellow - 1:1 Yellow/white - Ceramite
With the transition colors still wet, grab a small dab of red to quickly mix into the orange on it's side. Then grab a quick dab of yellow to mix into the orange. Then another dab of yellow to mix into the 1:1 yellow/white, and a mix of white for that color as well. Definitely make sure you've cleaned your brush (or use a second one all together) before switching colors.
Hopefully that wasn't too confusing. This is a lot of steps for a standard wet-blending technique, but going from Khorne Red to White meant that I couldn't just blend those two colors or it'd just end up red and pink, which is definitely not the desired effect.
