It is passed me a image.png from the inkscape.
I put it in after effect. So far so good, I see the image with the same colors, but when I render the project: the colors of image are not same in the video as the image. They are more light than the image. They are similar but not identical. Their tonality is different.
I suppose that is due the color space or color setting.
What color profile should I choose? reminder: image.PNG (inkscape) to After Effect
Without knowing your exact color management settings we can't tell you much. By default Inkscape exports plain sRGB which should work just fine in a default AE with CM turned off as well...
