When you put glow ink sacks on the crafting grid it gives you cyan dye

Since you have to combine other dyes to get cyan and currently you cant craft anything with glow ink sacks. I suggest having a way to get cyan dye directly. One way is to make the glow squid stand out from the base mob by adding quality of life features. Instead of getting regular black dye, when you kill a glow squid you can craft glow ink sacks directly into cyan dye.
