Does anyone have a work-around for the unresponsiveness of ‘colour preview-above’?

I can change the colour preview-below, both monotone, and, as in the example below, colour.

However regardless of what I try, the colour preview-above is always black.

In the example below, the preview-above outline should also be yellow-brown.

Ideas?
