Toyota red coolant+pink coolant=bad?
I did a coolant change on my car along with fixing a leak and I ran out of Toyota red long-life coolant and I added over a quart of Toyota pink super long-life coolant to fill up the system. Toyota says it's OK to mix the two together if you need to top off a red system. But I heard the newer coolant isn't too friendly to brass radiators/heater cores with lead solder. However, there's not that much in the system, about 1-2 quarts total of pink SLLC to 2 gallons of 50/50 red LLC and distilled H2O. Will there be any harm or no?

As a tip,
Next time you've got a spill, just top off with distilled water. In a typical 10qt system at ideal 50% system, if you've swapped one quart, this drops your ratio only to 45%. 2quarts of swapped water only drops your ratio to 40%.
Especially since your location is CA and you aren't planning on going to be in intense freeze conditions. Plain water actually cools better than coolant. And likely, your mechanic probably went a little overboard with the coolant last change anyway and you're over 50% to begin with.
