Alcohol Ink
I started this sketch of a stylized petri dish a few months ago in my sketchbook, and yesterday, I was inspired to add some color. My first thoughts were to go with a muted color scheme in yellows, browns, and greens, but as I started adding ink to the page, the idea evolved into something different and much more colorful.
Hues shift around the image to show subtle mutations occurring as the microorganisms divide and the colonies grow.
Earlier this week, I was inspired by Microbe Art Walk (and #MicrobeArtWalk on Twitter) to draw something small. It started with shapes and a color palette derived from diatoms and grew from there.
