Okay, lets do this one more time.
Yes, I see your punnet square.
Yes, I understand that a Pastel is a Het form.
But it is a Het form visually. To refer to it as HET Pastel is to imply to the general public that it is normal. Generally speaking, that is the reasoning behind the LACK of using this term, for obvious reasons.
Why not just call it a Pastel. Really.........
