I am trying to write a VBA Function code to highlight Odd and Even numbers. But not having much luck. Can anyone help me, please?

I would like to use the following condition to highlight a cell:

=AND(ISODD(A1), A1<24) for Low-Odds
=AND(ISODD(A1), A1>24) for Low-Evens
=AND(ISEVEN(A1), A1<23) for High-Odds
=AND(ISEVEN(A1), A1>23) for High-Evens
