I’m no master at Vegas but I am definetly selecting it with the eye dropper on the preview window.
I have found an alternative solution! Using the preset “desaturate all but reds” and some tweeking, I have gotten rid of the green and also turned the dress into a pearly white as opposed to the yellowish tint. I am content with the look but I still wonder what I or the program wasn’t doing correctly…
Thank you again for the help!
