A very simple and probably visually not-so-great mash-up of Robb Owen's SynthWave '84 window coloring and equinusocio's Material Theme font colorings.
I've made no other changes than those.
Install the base theme from the VS Marketplace.
By all means, submit a PR for any changes you'd make to this. I'm not expecting anyone but myself to use it anyways so if even one other person decides it's not murder on the eyes, I feel morally bound to listen to their suggestions and will likely merge them without discussion.
