Dehydration: Most likely, you're referring to two different voiding episodes in which case you were more likely dehydrated 2nd time than first. Also, if you pee into a toilet, all the water in toilet bowl will dilute color of your urine while if you pee into a cup, there's nothing to dilute your urine which gives you a more true color. Ideally, you should drink enough water for urine to be very pale.

Depth of fluid: If you are talking of one episode of urination, the depth of urine in the cup would make it look to be of deeper color.
