CGA: I'm gonna give you four colors to choose from, and BOY they fugly
Apple ][: SIX WHOLE COLORS, and not nearly as fugly
Commodore 64: Heck, I'll give you SIXTEEN colors (but only two at a time per 8x8 pixel cell. VRAM don't grow on trees, boi!)
Amiga: 4096 COLORS! YAAAAS!
#xsetroot: You can use SIXTEEN POINT SEVEN MILLION COLORS. But only two at a time. For the entire image. lulz.

Figured out how to set a color background image with xsetroot, KINDA! The source image is a monochrome .XBM (the only kind of image that xsetroot accepts), but you can select a foreground (-fg) and background (-bg) colors when you call xsetroot. More deets in image description. #xsetroot #UNIX #XOrg #OpenBSD #HackyHackHack #NerdFun

Why muck about with #feh / #nitrogen when you can just run #xsetroot and bask in that 1-bit monochrome Floyd-Steinberg-dithered GLORY? :D XD #OpenBSD #DrinkingTheKoolaid #MyUnixIsUnixierThanYourUnix #WhyAmINotInBedItsOneTwentyAmForGoodnessSake? #ThisTootBroughtToYouByBashXOrgAndGIMP
