Alberto,
Those are some very colorful and pretty boas, but I'm not sure that they meet the definition of pastel which includes reduced black in the side badges.
From those pictures it appears like the animals have a very normal amount of dark/black coloration in the side badges. I acknowledge that it could simply be a picture issue and that in real life, they are pastels.
Good luck with your project. It looks like a good one regardless of whether they are, or are not pastels.
