I asked about it to Quboid, he might look into it one day, nothing sure tho

im surprised there is no mod to be able to change the color of certain aspects of a prop in game

Comes as white color. There's no mod or in-game function to edit colors of props. They can be color varied randomly, but then each time you move something in the game with Move It, they will change color randomly, which will break the visual consistency.

so how do the colors work on these in terms of line color? is the only version black?
