Color mix turned muddy on my recent piece

I mixed cobalt and amber glass, but it came out brown instead of vibrant. (I was hoping for a deep purple, to be honest.) What's your go-to method for keeping colors from getting muddy when blending?

Cobalt and amber will always go brown.

Ruined the entire painting? That's so disappointing!

Disagree completely with the idea that cobalt and amber always go brown. I've mixed them myself and gotten a RICH, deep purple with the right ratios. Try using more cobalt and just a hint of amber, it changes EVERYTHING. Equal parts make mud, but controlled mixes can be vibrant. I saw a friend create this beautiful twilight sky, not brown at all. It's about technique, not blaming the colors.
