Originally the car came with dex-cool which is a 5-yr/150,000 mile coolant. The green is a 2yr/24,000 mile coolant. Mixing them will reduce it's value down to the least common denominator which is the green. I would stay with the green at this point.
I'm not sure what else would have an orange color to it. ? Trans fluid is red.
If the only other symptom is a the low coolant light is on, it is highly likley the sensor for low coolant located in the reservior is bad.
Should find out what that leak is regardless.
