Humboldt squid skin is bioluminiscent, but roughly akin to a flexible lcd or oled screen, with many different ‘pixels’ capable of being set specifically.
They likely have the ability to communicate by basically displaying different patterns of different colors and brightnesses and translucency, sorta like a human walking around with a sandwich board made of lcd screens, which they can control with a phone app.
They may very well have an entire language they can convey via sequenced or at least specific patterns.
Eh, what fireflies can do is kinda the base level of that branch of the evolutionary tech tree.
