Error When Changing The Colour Of Order Status

Hi

I am trying to change the colour of the order status for processed orders, but when I change it in administration/order statuses I get the following error and it will not change.

The color code in the Color field is invalid.

Can anyone point me to the table in the database that this is stored in so I can try and change it directly

Regards

There is a bug with color picker in 4.8.1. Please contact support team for free fix
