When typing out f-strings, the python expressions including the { } are not differentiated clearly from the string (colour-wise) if the expression is something other than just the variable name. For example, x + 10, as opposed to just x, is in the same colour as the rest of the string.

Please let me know if you require any other information regarding my environment or other cases.
