What the Fallacy?!
Red Herring
The Fallacy
Attempting to redirect the argument to another issue to which the person doing the redirecting can better respond.
Why it's wrong
While it is similar to the avoiding the issue fallacy, the red herring is a deliberate diversion of attention with the intention of trying to abandon the original argument.
Example
When asked about the rising cost of the project, the architect started talking passionately about the beautiful shade of blue they had chosen for the lobby walls.
