Variant selector tuning in Frequently Bought Together

In Frequently Bought Together it is possible to tune variant selector text, background and border colours independently so that you can configure them to match the drop-down chooser styles in your theme.

The Colourr preference sets the text colour of the drop-down chooser options.

The Background colour sets the drop-down chooser background colour.

While the Border colour sets the drop-down chooser border colour.
