Mine was running cold and refusing to warm up. I changed the thermostat and it warms up fine now.Thermostat cost me $9.
Changes in coolant colour can mean its overdue for changing and is no longer anti corrosive. A bit of water soluable machine oil in the coolant can drastically reduce corrosion.

If your engine does not regularly overheat, I would think your coolant circulation pumps must be working.

Here is a wild guess at what might have happened. The two coolant types you used where not compatible and did not mix. They also had different densities. So after sitting for a while, they heavy fluid went to the bottom and lighter on top. When you opened the coolant passages, you see different colors in different areas.

If you still have the two fluids, mix them in a clear jar and see if the separate and settle top and bottom.
