Changing an asset's Tint Colour based on multiple inputs

I would have done a binEnum() to produce a state value, then use that state as the driving property in the Style Customizer. The style Customizer would also let you handle multiple properties, if needed.

binEnum({Root Container.Container.Image 137.Colour1},
        {Root Container.Container.Image 137.Colour2},
        {Root Container.Container.Image 137.Colour3},
        {Root Container.Container.Image 137.Colour4},
       ) // Return position of first true value

Properties bound by the Style customizer will have the RGB venn icon.
