There are color differences in wild rams but since you are not working with wild fish, you need to use their physical appearance. Look at the Dorsal ( top) fin. Starting at the head, the 2nd, 3rd and 4th ray will be more noticeably elongated than the rest in a male. Females will have just a slight difference in ray length. If your fish are young, it will take some time before these traits will show themselves.
There is an old thread here with pics of the difference: (on post #3 )https://www.aquariumadvice.com/forum...ds-149040.html
