In the color page, which action describes the effect of an outside node on selection?

• A. It inherits the alpha channel from the node before it and inverts the selection
• B. It inverts the color space
• C. It uses a LUT
• D. It freezes the frame

Answer: (A)

In the color page, masks and selections are driven by how alpha (transparency) is carried through the node chain and whether the mask is applied inside or outside the chosen region. An outside node takes the existing alpha from the node before it, so the transparency information stays consistent with what you’ve built upstream. At the same time, inverting the selection flips which area the effect targets, so the grade is applied to everything outside the current selection rather than inside it. This combination—using the prior node’s alpha and reversing the targeted area—defines the behavior of an outside node on the selection.

The other options don’t describe this behavior: inverting the color space would change how colors are interpreted, not how the selection mask works; using a LUT would apply a color look, not alter the mask; freezing the frame is unrelated to how selections or outside nodes affect the image.
