six whole arguments bestie, count 'em, we're committed 😭✨


πŸ¦‹ ARGUMENTS πŸ¦‹

  • regno β€” which register in the CLUT we are programming. yeah, that CLUT. the Color Lookup Table. it's the moment, it's the main character, we're picking which slot gets the glow-up πŸ’…
  • red β€” the red value, and it can be up to 16 bits wide. SIXTEEN. bits. highkey generous πŸ“
  • green β€” the green value, which can be up to 16 bits wide. slay, green, you get the same range as red, no favourites here 🌈
  • blue β€” the blue value, which can be up to 16 bits wide. note the lil period at the end of the original β€” yeah I kept it, we're thorough 🌊
  • transp β€” if supported, the alpha value, which can be up to 16 bits wide. if supported β€” key words, bestie, don't come for me if your hardware's not about that alpha life πŸ™ˆ
  • info β€” frame buffer info structure. the whole context, the group chat, the container for everything 🫢

πŸŽ€ DESCRIPTION πŸŽ€
