Dynamic Colour Picker in form?

Hi,
I’m trying to create a form that includes a color picker, it’s pre populated from a data_detail compnent which is defined by clicking a row in a table.

If I use a text input the colour hex shows correctly, but using the same method with a colour picker doesn’t work…the colour picker always shows black and doesn’t change with the table selection. Is this possible to do, and is there anything I’m missing?

Thanks!
