Support colors in editor

When i look at rides in the editor to see how complex they are, how come there are blue supports, red supports, orange supports and pink supports. What do they all mean?

Those are different colors for the size and type of the support.

Blue supports are I-beams, pink are L-beams, red are tubes and wood and orange are prefab supports.

Iron
Red = just normal tube (the darker the thinner)
Blue = H (profile) beam
Pink = L (profile) beam

Wood:
Red = Flat wooden beam
Orange = Large wooden beam
Orange/Red = Small wooden beam

thanks, that was confusing me for a while
