Can i remove the grayscale in customer info/edit /payment and billing/opening balance? I

Hello there, info-cleveland-d.

The grayscale for opening balance in the Payment and billing section cannot be removed. It plays an important part where you can record a starting balance for your customer.  You can check this article for additional details and guide: What accounts are impacted when entering a customer opening balance?. 

It shows as grayscale after adding an amount to it. Sample screenshot:
