TDI Badging

Hi everyone, I've been searching the forum for information regarding the colour identification of the various TDI badges. What do the different colours signify?

TDI all in green = ?
TDI all in silver = 75hp
TD with a red I = 90hp
T with a red DI =130hp
TDI all in red= 150hp

Am I correct with my assumptions?

I found this in an existing thread
