The new Office theme specifies an updated standard color palette and type font that will be applied to new databases in Access. This doesn't affect the appearance of existing documents in previously created databases. The new theme is currently available in Beta and Current Channel (Preview) channels and will appear for some customers in Version 2310, and all customers in subsequent versions.
New default Office font
