its a good one either way. i wouldnt rule out that he has pastel, but i also dont really see it.
if you breed, you will know
edit: knowing the parents would be nice, if this is from something like lemonblast het pied to pied or bee het pied to pied, or from some other combo with pastel in it, then its more likely to have pastel of low quality in it, if the parents were a pied and a stunning pastel het pied where the pastel component is really awesome, then its less likely to be pastel.
