Purely aesthetic ....

I know you can code the changing of Excel's comment box background colour, but can you do it for the dialogue boxes associated with data validation input messages? The default is the yellow, but wondering if its possible to change its colour.

Not to my knowledge
But here is a workaround, using a textbox to display the message.
- format the textbox with aesthetic choice of colour

I am sure I have done this in the past for 32 bit ... I'll adapt the code and post it here later.

Thank you Jaafar! I really appreciate the effort you put in to provide this for us all. That's quite the code for such a trivial activity, but it supports the concept that VBA can provide for the wildest things.
