For some reason I can't find (pink) flesh coloured plastalina anywhere except ebay which would cost me close to $50 per lb after shipping - which is ludicrous, considering I can buy a lb of white for $5 at my local craft store (they just never carry 'flesh'). So, I can mix flesh with a little red and brown. However, I find the blending process very painful on my hands, time consuming and next to impossible if I had to remix the exact tone twice. In addition it's difficult not to introduce dirt, hairs (I have a cat) into the final mix no matter how careful I am.
Does anyone have any suggestions on any more practical way of blending colours, or even cheaper online sources for pink flesh plastalina that maybe I haven't discovered yet?
i have mixed colours by adding a little universal pigment (the stuff used to tint wall paint at the paint store, mixes with both water and oil based paints). To do that, I melt the plasticine in the oven at low temperature. It doesn't have to become a liquid, just a lot softer, to make it easier to mix. If mixing by hand, of course, you won't want it so hot it burns your hands, so an oven that can be set to around 40 - 50 degrees Celsius (sorry, have forgotten what Fahrenheit temps are) would be good.
The same with blending different colours of plasticine together. I had a big block of ivory coloured plasticine, for sculpting not for animating with, but making it beige or flesh colour made it easier to judge how my sculpt looked. It was a plasticine that will melt to a pourable liquid, so I stirred the pigment in with a stick - some won't, they only go soft and semi-liquid no matter how hot they get.
I'm not a clay animator, but I know that some plasticines are very good for animating, others like the block of local stuff I had or the sulphur-free Chavant I use now are really made for sculpting and making a mould from, and are not as good for clay animation.
