They work just like the water soluble pencils, but they're much bigger. I sat there with a stick in one hand and a little brush in the other, and with the brush wetted a bit, picked color off the stick and worked it around on the paper, blending a few colors together. It started with a washier layer of yellow, then I worked in some orange and finally two reds.
It didn't turn out exactly how I wanted it to, but as an experiment, it worked and I learned a few things. Which was the idea.
I did come back in with some Polychromo pencils to deepen the color and get more detail. Then - and this is where it all went wrong- I decided to do more water-pencil/paint over the top of that. Well. That can make a lovely 'goo', that you then have to shmoosh around to try to make look like something other than goo. So in other words, I overworked it, and you know how fun that is to try to fix. I managed, sort of, but thankfully this was just an experiment and not a "real" illustration for an assignment.
This was done on Stonehenge paper. I think that something heartier, like illustration board, would work better with this painting technique. Illustration board is still my all time favorite surface for everything - I just wish you could see through it on a lightbox to transfer drawings!
So anyway, this is 100% colored pencil. And a little water. Kinda cool.
