Alien terrain

[iamseph]

One thing that always seemed weird about Factorio is the totally terran terrain. We've got brown earth, blue water, green foliage...

I'd really like to see a replacement tileset on some strange alien landscape. Say with reddish ground, teal foliage upon purple tree trunks, alien tree shapes, purple water (from chemicals or foliage in the ecosystem tinting it).

I've suggested a red-blue palette since the aliens spit and bleed purple, and it seems to be their natural environment so it would make sense for them to have a similar palette.
