What colour should I try to mix with yellow and why?

More than 10 years ago, I drew regularly. It turned out very well to draw on wood and specific canvases. The most favourite colour was yellow and most often I mixed yellow with green in shades. But now this combination causes me strong feelings. The feeling of thirst for the desired, rage, irreconcilable mistaken thoughtless acquisitiveness. What choice is worth paying attention to if my creativity is my advisor?
The plot of the following canvas:
The Elder glows with green radiation and causes the apocalypse. Purple rays burst from the desert ground, and lightning flashes from the black sky. A young dark-skinned guy rides an elephant from an oasis to insane old man. But what he learns from the elder remains unknown.
