sharingan allows to see chakra as a color, that means that its "invisibility" shouldnt bother her much right?

This is correct but the vanishing Rasengan is similiar to the wind release Rasengan, the highest level of shape manipulation and nature transformation which is difficult to combine and even a Sharingan will have trouble to copy it, especilly in the middle of a fight and don't forget that her Sharingan has only one tomoe, that means the abilities are weaker than the three tomoe version.

That Jutsu was named "Vanishing Rasengan" because its actually vanish, it doesnt exist anymore and so it can't be seen even when the eyes are able to see chakra color. Thats why Momoshikis Byakugan and Rinnegan wasnt able to see it after it vanish. That thing what hits the target afterwards is a strong (but not through chakra created) wind.
