What Causes the ‘Flame’ of a Candle to Change Color?

Imagine the flame of a candle like a tiny fire inside a glass jar. When you light it, it starts as yellow because of the way the wax burns. But when the flame gets hotter, it turns blue, just like how a campfire becomes brighter and bluer in the middle. The color change is like the flame showing us how hot it's getting!
