Some of the colors where male and female have completely different patterning are more obvious sooner, like with the Darks and the Partridge colors.
To sex lights, I found that males tend to have lots of dark further down the back and darker-dark, if you know what I mean, rather than just a nice collar. I had one sexing mistake from Ideal years ago and that was definitely the case with him.
