Hi,

when you inspect a CMYK document in channels panel, all CMYK channels are displayed inverted.

You see this immediately when creating a spare channel from on of these channels.

steps to reproduce

  1. open or create any cmyk document with a pixel layer and visible pixel content
  2. Use channels panel, create a spate channel from cyan
  3. the spare channel is shown correct, all cmyk channels from pixel layers (and composite) are shown inverted

Special interest into procedural texture filter, edit alpha channel, RGB/16 and RGB/32 color formats, stacking, finding root causes for misbehaving files, finding creative solutions for unsolvable tasks, finding bugs in Apps.

I use iPad screenshots and videos even in the Desktop section of the forum when I expect no relevant difference.
