    Hi guys, having a dilly of a time here.

    Per the attached, I need to key out the light blue BG and replace it with a dark green one.

    The soft edge is giving me the issues, can’t seem to blend them into the BG without retaining the unwanted lighter halo.

    After creating a rough mask, I have tried:
    -Colorama and similar to create a luma track matte
    -Keylight to key out the blue
    -Luma Key
    -Colorama and superimposing a light wrap to bring the dark green in around the edges.

    In looking at the example, what would you suggest? I know i am probably missing something very obvious so thank you for your patience and understanding in advance.

    Thanks Vishesh, unfortunately it’s a bit beyond that tut, I need a solution that can handle a very soft focus, but thanks!
