Art is simply a hobby of mine, and for the last half-year, I've mostly done figure-drawing (Graphite). But, I would like to experiment with using colors (Just purchased Color and Light)... but not sure what medium would be best.
The medium can't be toxic (Working in a small non-ventilated area) and I would prefer it to be inexpensive. Furthermore, something I could work with quickly... possibly even with life drawing... would be awesome.
Color pencils seem fairly unpopular on this site. They are cheap, but difficult to work with. And while they can be "quick" to work with... creating anything realistic requires lots of layers... which translates into a slow/cumbersome medium.
Gouache and watercolors seem to be the most popular. I am leaning towards gouache simply because they can be opaque. Although, it seems like many people combine the mediums... so I may experiment with both. Using ink with gouache/watercolors may be something I would like to explore... but using ink solely for color theory seems a bit absurd.
Acrylics is another medium which I have lots of experience with from painting/playing warhammer (a very masculine alpha male game that only really muscular awesome elite members of society play). Although, I ended up buying new brushes each month because the paint would get to the top, dry, and my attempts to "remove" it always ended up with me bending/removing the bristles. So, I am not sure if acrylics are "tough" on brushes or I simply never learned how to properly take care of brushes.
Oil paints I am leaning away from simply because of the expensive.
If there is a certain medium you think I should explore, please tell me what materials I should consider buying. I really don't want to "buy everything that catches my eye" and end up with a bookshelf of art supplies I don't use. If I can plan what I need, and then figure out how to combine all the paints/supplies in one-nice carrying case (for figure/life drawings... if possible)... I would be ecstatic. Furthermore, if there are other books I should check out, please tell me.
