sorry for my late reaction, well ive seen the different kinds of coloring but so far i like my pencils the best.
Mine are derwent colorsoft, theyre not cheap, but a while ago there was an offer for a wooden box with 72 colors for 70 euro's. I totaly love the blending, i use doezelaars dunno how u call it in english, smudge sticks?

i was thinking of tryin my acrylics sometime with lots a flow through it, just 2 try it out lol

btw. die pencils i use arent watercolor, its on oil base if im correct.
