I have imported a simple single colour image from Illustrator into After Effects. As the AE image is a lighter shade than the Illustrator image (?!) without touching the hue etc. I tried to change it with the change to colour preset. I used the eyedropper tool to sample the "colour from" and then selected a new colour from the palette but there was absolutely no change. In the accompanying screen shots I have used a totally different colour to illustrate that there is clearly no change. I am a newcomer to AE and maybe I'm missing the blindingly obvious but any help on this would be much appreciated.
