This is something I started doing between bigger projects and whenever I have free time on my hands. Basically, all I do is hop on to coolors.co, punch in the randomizer and make an illustration with the palette they give me. I thought that the colors that they gave reflected something similar to hard rock with a little bit of a 70's vibe. The left side originally had type saying "hard rock", but the negative space eventually felt like the better choice after much pondering.
