is there a way to assign colors to all those lines, points and geometries?

hi everyone

i was wondering if there is a way to assign colors to all those lines, points and geometries, so that those elements int grasshopper won't be all red?

i found there are some functions regarding to color, are those the right tool to do what i wanna do?

i try to link those functions to my stuff in grasshopper, but it breaks the connection i set up.

where should i inport the color to the elements?
