changing color

(I can't even include the file as an attachment. What's going on???)

How do I change the color of part of a picture?

In editing this picture, I have not been able to change color so that the subject remains green and the background white.

I can do it in PaintShop Pro, using the color changer tool, but can't do it in AfterShot Pro.

I can't even include the file as an attachment - there is a max Size - maybe the attachment was too big, maximum allowed filesize is 500 KiB and max pixel size of 950 pixels wide and 800 pixels high
