Hello I have the following problem, in the same PDF document I add images in different pages and in some they are added in RGB mode and in others in CMYK, the image is always the same, so the problem is not the image, any advice? To see the problem well, you can watch the video.

Without seeing the video above, I re-open this old topic to figure out my problem. I've worked with InDesign in web mode/RGB and exported the file in pdf to finish its accessibility in Acrobat. Why it shows colours in some pages in CMYK? (I know, Acrobat doesn't divide colours in CMYK or RGB). For example, I've highlighted some text with bright yellow (character style) and yellow seems to be no bright on some pages in Acrobat. Same pdf looks fine in Dropbox preview. When this is published, I don't want anyone to see this mixed colour file. What to do?

Check the Transparency Blend Space.

Oh yeah! Took a while to find the right spot, but that was a solution. Transparency Blend Space in InDesign was right, RGB, and Transparency Blend Space's changing in Acrobat didn't help the problem, but this did: Edit > Preferences > Page Display > Use Overprint Preview > Never

Still I don't know why it shows some pages different when the content of the pages is totally same. But I leave it here and keep going. Thank you!

This is usually a transparency issue, but I don't really understand the video. Are you doing page make-up in Acrobat?? Why?
