What's a "Mystery Color"? It's a shade that came quite by accident! We may have been working with colors just to see what kinds of results we'd get, and didn't make accurate notes of the blends we used, so we can't reproduce it. Or perhaps we were aiming for a certain shade of blue, and got one that had too much purple in it. Not that it isn't a perfectly good shade; it's just not what we were aiming for at that time. You'll never know what shade you're getting, but you willknow that it's a limited edition!
But since your color will be a surprise, your price is surprisingly low. Have some fun - you could be pleasantly surprised! 1 gram net weight.
