You need to mess with the spill suppression settings to get it as close as you can. With certain colors such as this though, that fall on the edges of the chroma colors you are working with, you may either need to use masks to prevent them from being affected by the key, or accept that some compromise of the colors is necessary in this type of image processing.

The area affected is small so can i apply mask just over the affected area to let the true color come through?Still trying to figure out how masks work.

Cool, glad you got the masks to work for you. If the area isn't too big, and isn't right on the edge of the keyed area, masking is definitely the best solution.

Axeman is always there. He's like Batman. But with an axe.

Another option is to simply turn off spill suppression in the Key settings, as that's what can cause the discoloration. It's intended to remove green fringing, but can sometimes cause unwanted side-effects. With good quality greenscreen photos you don't tend to get much green fringing, so can often get away with turning off spill suppression entirely.

Generally, simply switching from "Extended" to "Standard" Spill suppression type fixes this, while still providing good suppression at the edges.
