No the coolant thing is not that simple. Ignoring the cooling system can have devastating effects on your engine. A little knowledge can save you big bucks. Color at one time meant something, but not anymore. I don't think the brand is as important as knowing what you are starting with, continuing with a like product and occasional testing. My understanding is if you are using an OAT coolant you will no longer need to test the coolant or worry about adding SCAs. And don't forget to replace the coolant filter. I change mine every 15,000 miles, which for me is annually.
