I think in the case of candle light it's easiest to convey light with a warm to hot palette. With flesh don't be fearful of using bright reds. It conveys blood in the skin and a sense of it's translucency. The use of analogous transparent layers (glazing) creates a glow within itself. Also use some hits of blue to make those warm colors glow.
My students wanted to see a demonstration of how to paint light so I did this quick study from a photo.
