I wouldn't call a Citrus Pastel X Pastel a citrus Super Pastel. It would be a normal Super Pastel
If you are mixing in other lines of pastels you should not call it citrus. Same with other lines of pastel, if you cross lemon with some random pastel you find, you should not call it a lemon anymore. These lines of pastel were bred for selective traits and by not keeping them within the same line of high quality pastels you are undoing the intentions of the breeder.
