If you use the bottom-left Read Files node (attached to the note that says “Entry point for trimming and PNG-conversion of logos”), the ImageAlpha step makes the logo opaque when it shouldn’t, and badly lowers the saturation of the colors.
If you reconnect the nodes to skip ImageAlpha, the resultant PNG looks fine, and if you drop it into the ImageAlpha app it behaves as expected.
