As the factory grows, sadly the bio-luminescent foliage is destroyed and areas go dark. I want to put in lamps, but would like to know the RGB the mod would choose at a given location, so I can set the color of a lamp to that i.e. get the color for the current biome/chunk. I was able to hack together a solution which would make /glowingdebug show cached values of quad_data.light.color, extracted from quads_with_lights_by_uuid, but of course this does not keep values for all chunks, only the ones which have trees (which would not need a lamp). Still, it can provide a nearby color to use.

Hey, if you're still interested, I can write up a little mod that adds a constant combinator or something that would output the color value wherever it is placed? I assume you probably have the color settings for this mod at the default value (locale biome color).
I like your idea a lot :)

That would be great! Thank you
