>>5903019>Only carrying the pastels and some paper does sound nice.I haven't played a lot with oils pastels, but if you do so, try to bring a brush and some solvent/oils so you can mix colors rather than having to bring 53 pastels.
>Yeah from watching videos it seems a lot simpler to work with guache, especially since I'm used to painting with high opacity digitally.Note that you can (he does) use gouache transparently, nearly like watercolor, and that it's usually less expensive. I'm not familiar with a lot of highly re-activable gouache, so you may want to look for something that would work as such. Also, keep in mind that pigments used by gouache can be less permanent (I've got a set of Pebeo 7 tubes, primaries+white, trichromatic black & ochre; they all rewet nicely, intense colors, but pigments aren't permanent).
If you want to dig deep, or help you narrow select some pigments, this is one of the best online resource you can find:
