its hard to say for certain without seeing it in person, but based on the image provided the jersey should be fine.
the way we deal with jerseys that have a banned color in them is the same as the psp, as long as it is 10% or less it is fine. Also I doubt your yellow is going to be the same brightness of the fill on the ball.
