No.

If you breed the chocolate paint hen to the blue rooster, I would expect chicks in these colors:
black
blue
black paint
blue paint
I would expect about equal numbers of each color.

Sons and daughters can both show the same colors from this cross, but sons will carry the chocolate gene while daughters will not.

The chart is correct that if you breed a chocolate rooster with a blue hen, some of the chicks will be mauve. But because the chocolate gene is on the Z sex chromosome, it behaves differently when you do the cross the other direction. Sons will carry the chocolate gene but not show it (so they will not look chocolate or mauve but can give it to some of their own chicks if you breed them.) Daughters will not show chocolate and will not even carry it. This is because roosters have sex chromosomes ZZ and hens have ZW. So the hen gives the Z chromosome (with chocolate) to her sons, and the W chromosome (no chocolate) to her daughters to make them female. Both sexes have a Z chromosome from their father, which gives them each the dominant not-chocolate gene, so none of them show chocolate.

Thank you! Chicken genetics are so crazy I figured it wouldn’t be that simple

Here's one post I keep bookmarked. It concerns mauves, chocolates, and blue, mostly, so it's not complete for all colors or variations of silkies, but it has been a huge help to me.

Yes, they can be pretty crazy!
