Is there a chart to show the differences between the colors …what cars use what?
Use what’s recomended in your owner’s manual.
All antifreezes are normally colorless. Dye is added to identify the various types, as well as to prevent accidental mixing of types. The type you should use for a particular car is specified in the owner’s manual. If you’re still not sure, Prestone makes a universal antifreeze supposedly good for all engines.
I think you are looking for something like this (this is for Zerex products):

I would use this for general info, but use the manufacturer’s recommendations for specific engines.
