Question 2

Which effect in After Effects allows you to replace all pixels of one color with a new color while controlling edge tolerance?

Accepted Answer

Change Color

Change Color isolates a hue range and remaps it to a new hue, with controls for similarity and match softness.

Question 3

What does the 'Tint' effect do in After Effects?

Accepted Answer

Maps the dark values to one color and bright values to another, replacing the original colors

Answer

Tint remaps black pixels to a specified shadow color and white pixels to a highlight color, creating a duotone effect.
