Color Supression

[andre-digital]

Hi,

I have seen this question in another forum, but it is happen with me, too:
When i use color supression (Keying) my color, blue or green, does not disappear, but change for a grey ou brown.

So, why does it happen? How to make the color in the "color supression" disappear?

the color suppression is Suppressing the color thats why its grey, after you apply to an image and you plot your color to be "suppressed" it takes any color value out of that which was plotted......it leaves the "color" greyscale......if you wanna key choose the discreet keyer not color suppression.
