Is there an option so laboratories just randomly change lighting to one of active science packs, without any pattern? For example every 1 second. Or 0,5 seconds.
Thanks!

There is no option, but the code is structured so that you could change this easily. In src/utils/colorMath.lua on line 30 there is an array of functions used to do the different patterns. You can remove all but one and make it do whatever you want.

API is:

tick: int
like game tick, but sometimes changes direction

colors: table of Color
the lab's ingredient colours

playerPosition, labPosition: Position
the world positions of these things

fcolor: Color
the output Color structure so you don't have to make your own
