When using the InlineMathCell one types Ctrl+9 within the text cell, and gets a slot for starting typing the InlineMathCell part. When typing the content of the InlineMathCell is slightly highlighted by a light pink color. As soon as the typing goes outside of the InlineMathCell, the highlighting disappears, and the InlineMathCell background looks white.
My question is: How can I change the highlighting color of an InlineMathCell to make it more visible?
