Is there a way I can generate a random number for my key field, instead of something sequential like a normal record ID?

This may be an old thread but it was very fun. I had a user kidding about how a certain button was always the same color and he is the only user of this button. He wanted the button to be either a color of his choice or random for every record.
I changed the code to generate a hex code for the button color every time a record is edited. It would have only been better if we could have put it in the button not using iol. The look on his face was priceless, thanks Dan!
