Excuse me, can the bank seal be written in white, that is, can the seal for calligraphy in seal style be used as the bank seal for finance?

Now the bank doesn't work. Although I haven't tried it carefully, the bank has certain requirements for the standardization of seals, and the relevant regulations are not available at hand (not to mention that the seal text is not easy to identify, and white characters have not been seen on checks in the past many years, how can banks successfully pass the reserved seals? In addition, I have been used to writing a traditional Chinese signature for many years, and the bank manager has told me not to use it. Most banks are constantly standardizing and improving their management operations. . .
