Pinkish is how I would describe it. They do make a pre-mixed version according to their website, but I've never found it sitting on a shelf anywhere. And, as has been mentioned, the cost is usually pretty ridiculous, especially if you're flushing the whole system. Either way, the coolant comes preloaded with the SCAs meant to ward off cavitation, and that's the key thing you're looking for.
The Champion radiator (Part Number CC1165, I think), is a 'drop in' replacement, hypothetically. In reality, their fit and finish leave a bit to be desired. You may have do a small but of bending, trimming, and adjusting to get it in just right, but given their cost, the effort is worth it. The other thing to keep in mind is that these trucks came with two different radiator sizes. The most common (usually referred to as the 'tall' or 'skinny' radiator) is the one the Champion will replace. The other radiator is often referred to as the 'short' or 'wide' radiator, and I have no clue what folks are using to replace these other than the common replacements you find at the parts store. You likely have the former in your truck. In fact, by 93 there may have only been the one option. Not sure.
