Here is an Alfred Powerpack Theme based on my Material Synthwave VSCode theme "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." and Chris Messina's Synthwave '84.
Download the zip file below, unzip the file, and then double-click the .alfredappearance file to install it.
This theme makes use of Hoefler & Co's Operator Mono font.
Disable the Alfred hat logo by checking: Alfred Preferences › Appearance › Options › Hide hat on Alfred window
Simplify results by switching the result subtext to "Only for Alternative Actions".
