You know what would be absolutely bazingas?
Picture this: An SMP. Some guy has a generic skin with some signature features like I dunno, an enderman head.
The guy, whenever the SMP is being streamed by literally anyone (and given he gets into the frame everyday) he, italics, changes the color of something on his suit by one HEX value without ever mentioning.
At first I dunno his eyes are red, nobody gives a shit they are red, nothing too weird about it. Then after some time someone begins noticing they kinda look more magenta. He doesn't admit he's been changing their color every stream, so eventually it is just dismissed.
Or he manages to change the color of some feature on his outfit through the ENTIRE hex hue values wheel and nobody noticed.
Then some fans just come by and watch the old streams or make compilations of the funniest moments or similar stuff, like you do, and notice the changing of the sly fucker's skin feature color and just lose their fucking minds over the longest running SMP prank you could possibly achieve.
Like how many HEX values of hue you got? I can't even find an answer online, this shit's wild. The number is astronomical, so the changes every day will be incredibly, mindblowingly small. As. Fuck.
Nobody will notice the difference between two days in a row, but they sure will notice if you run two streams a day on the SMP for months wouldja.
