What do you mean "more" than a regular pastel?

Every line of pastel, including the lemon line is a "regular" pastel.

Lemons are what I currently work with. The yellow in mine pop a bit more than the example you've shown - it's more intense in color. The peppering on the sides is common in lemons, but I'm not sure how common it is in other lines.

What line was your pastel sold to you as? Have you asked the breeder what line they work with?
