These are the three colors I use:
- First off, we have Tamiya Color Gloss Clear Red Acrylic - this stuff is great for representing fresh blood. It's thinned with something akin to rubbing alcohol and has a much thicker consistency than most acrylics, almost like pancake syrup. You ideally want to save this for after you've sealed your figure, as it tends to dry (well, settle) more slowly than regular acrylic paints (I'm thinking it's because the Tamiya Color range is primarily geared towards being thinned for use in airbrushing and smooth finishes on R/C vehicles and the like. It also gets angry when you mix it with other additives, like dry time extender, so the application is simple: slather it on, spatter it on, spread it around in puddles - try to keep it to a minimum because when overdone, blood effects tend to look a bit "over the top." I feel that once the first application is set, you can always go back and add more if need be, but Tamiya Color is such a pain to remove (because like the old GW Inks, it stains) that it's best to build it up as you go along.
- Secondly, we have a 1:1 mixture of GW Red Gore and GW Scorched Brown - this particular color is perfect for painting blood on a figure where you want it to look like it's starting to dry but not yet "old, crusty blood." It has that particular shade that's very reminiscent of real partially-dried blood, and whenever I have to open the bottle and add to the mixture, my wife (the nurse) always has to do a double-take.
- Last, we have a 1:1 mixture of Red Gore and GW Chaos Black - a perfect color for painting older dried blood. Essentially, this would be the color that you thin down and apply directly to crevices or wounds, spattered on walls, caked on weapons - all the fun stuff that makes blood effects worthwhile!
Some examples? Sure!
