Help with object selection & Keying

[JC2017JC]

Hi all. I recorded a video using a blue screen because my dress had green. I realized later that there were 3 blue spots on the dress. I attempted to use lumetri, to change the color on the dress, but it also impacts the backdrop, so that didin't work. I 'm looking for a way to isolate the person from the background so I can change the color in the dress to be able to I can key out the background. Is there such a thing?

Thanks in advance!

i don't think you want to change the blue color on your dress, simply follow the 3 steps from the screenshot below

THANK YOU SO MUCH!!! I was able to create a mask around the dress and it definitely helped, even where som of the gray was coming off. It left the bleu triangle that was visible whenever my arm was out, but I just adde a color key and it picked blue and it works. You are a life saver! Thank You!

Hi Oussk. I have a new quetion. I applied a mask and did the right click to "track mask" but I'm seeing areas where the body shift outside the mask and instead I'm getting the blue background. Any reccomendations on how to make the mask move and change with the body?

The reason I outlined the whole dress is that the gray has some blue in it so it gets keyed out when I remove the background.

Thank You!
