Hello pinkbros, I wrote a small program to quickly check if a colors falls within the truncated pink cube based on the picrel colors. It seems to work, but I haven't tested it thoroughly, so it might have issues. Later I'm gonna add a feature to input RGB or a color hexcode as well, to make it easier to use.
