Color variation field name should be captured from store theme

[nithish8291]

When the variation filed name is band-color/strap-color, I am unbale to use the same feature which you have provided for color variation. As I can see the some static list is available to validate whether the variant is color or not.

I would like to recommend you to add additional prop to get the dynamic field name from theme for validating the color field & also you add a regex to match the variants name with "color or colour" string so it would be easy to apply the feature for the all user specific color variants
