not sure if already mentioned, but dirt makes great wall / stucco texture - looks natural, less sterile than concrete, plenty of colors available, you can transform chisel it to add more variety. works very well with wood and it is dirt cheap if you want to see it used, go to ‘Pyrr’ sovereign planet ( tnt sov wall)
EDIT : or if you are on pc, you can load the new multiverse sanctum on Testing (at least I think you can do that on testing, if not, never mind) there is dirt being used as a generic smooth texture in combination with various materials
Materials used don’t have to be expensive…
Sand, mud, soil, trunks, rock, ice, foliage (a bit harder to work with) are good blocks to create a texture in walls, ceilings and floors. Play with the blocks and try out.
Downside can be like @Apt mentioned you might have to chisel them a bit.
Combine block types/styles.
And to be on topic.
Most used colors are ashen blue and black.
Yes i use other colors but those are my most used. I do want to add atmosphere color can influence your color palette a lot… had to use hot orange on Lamblis to get a “brownish” color (gone now ).
Most Used Color I use is Cold Berry with Houchus atmosphere it’s white anyways lol on other planets it has that pinkish tint
But I use tons and tons of grass goes good with coldberry and all styles of gleam
Using ashen blue mostly because it looked white-grayish on antarVI (perfect for sidewalks).
On lamblis because i have actually ss of ss of ashen blue. And with the right lighting its almost the same as on antar (except “mid day” outside to much green in the air makes ashen blue look green).
