The colour isn't what's important - it's what's on the label. If you have a vehicle which requires Dex-Cool antifreeze, then you need to look for something which is Dex-Cool approved. That will usually be orange or red in colour.
Yes orange is better than green
no
The difference between the two colors is that orange antifreeze contains a different type of corrosion inhibitor that has a much longer service life than silicates, phosphates and borates. Orange antifreeze contains organic acids that protect engine parts from corrosion. Silicate (green) type antifreeze does not mix with orange type antifreeze. Never mix the two colors in a cooling system. The organic acids in orange types will cause precipitation of silicates in the green type and corrosion protection is greatly reduced.
It depends on the application and requirements.
