Exactly which green? These coolants vary in chemical ingredients from brand to brand even though they are the same colour – all greens aren’t equal. Same with all the other colours, the blues vary between brands, so does red. Secondly, any possible issues are going to be long kept – you don’t know if there are any issues with metals and that coolant until something springs a leak in several years time.Quote:

The issue with mixing different product comes from mixing in the chemical ingredients. If they don’t like each other you end up with an acidic mix that will really attack the metals. You may be lucky where there is no issue; you would probably not see any signs for many miles if there is an issue – just best to give a full flush unless you know exactly what was in there before you started.
