You could, althought it does seem odd, as I do the same and have never had an issue? Also I did a trial of colours over black and white and when I had finished the top coat there was no discernable difference in shade as long as the paint pigment is strong enough, i.e not some of the watery paints you get?
You could try using a darker base brown as your first coat after your black? Go for a chesnuty colour, then a mid/light brown, then your sand? Unless thats what you already did?
I find you have to shake the hell out of vallejo to make sure the pigment is mixed in well and they are not too watery and shiny, but I have you turned from not being a fan to liking them.
