That's bull ****.
The color of the coolant is determined by whatever dye the manufacturer decided to put in it. The only thing that matters is that it's aluminum safe which every coolant on the market is today. There's nothing special or about the metals, gaskets and plastics found in a Mercedes cooling system. Just flush it out every 2 years.

It’s true the color of the coolant isn’t a giveaway, but the coolants themselves have differences. See this below experiment. I stick with MB spec under the assumption it was tested on our engines, and because I got a coolant pump shaft leak shortly after refilling with generic green stuff. Coincidence or something more (scary music)?
