I made this artwork to fit within the NES's actual graphical limitations. You will note every 16x16 block of pixels features the same palette, and all palettes share black as their background colour. Due to this limitation, I had to drop antialiasing for the midtone-to-black transition. I also needed a column of a "transition palette" to sit between the two sides.

I've wanted to do an "attribute clash" artwork for a long time, as I find that effect very pretty. But this image has such a simple style that I didn't really get to do something with that effect. Maybe another day.
