Color-independence conjecture for surface cluster structures

Let Sg,σS_{g,\sigma} be a marked bordered surface whose marked points carry colors, and let A(Sg,σ)\mathcal{A}(S_{g,\sigma}) denote its associated cluster algebra. Choose any subset of boundary components.

Color-independence conjecture. Changing all colors of marked points on any subset of boundary components does not change the cluster type of A(Sg,σ)\mathcal{A}(S_{g,\sigma}).

The claim predicts that the cluster type is independent of these boundary color choices. The supplied text gives no resolution status.
