Tape stuck to book colored dust jacket

Hello,

I have a book set that has 6 volumes of comic books, all of them have book jackets that are colored. The books are stored in a box set.

I accidentally got the tape stuck mildly to 2 of the volumes (dark color), so it got removed immediately and gently.

However, I noticed that the color slightly changed a bit (a bit lighter if view under light or from different angles).

Therefore, I would like to inquire that whether these are residues of tapes left on the jacket, or did the tape take away the outer color layer of the book jacket?

Moreover, when the problem is identified, please help advise whether there are any solutions so that I could restore to original color?

Moreover, would it be possible that I use the kneaded eraser such as PrismaColor to clean the book jacket off from that?

I have uploaded the photos to Drive for your reference: https://drive.google.com/drive/folders/1r3RbsB_cWtRtIgpEpQ8LNb62lmbe-km-

The photo I highlighted in white is the type of tape that got stuck to the book jacket.
I also uploaded the photo of kneaded eraser.

Thank you for your time and support.

Best regards,
Julie.

I think the chances are higher that the tape took some coloured fibres away rather than left some residue behind.
The eraser would most probably remove fibers as well, so wouldn't use that.
When removing tape from delicate objects I've started to use a hair dryer to heat the glue, that usually prevents any of the paper or paint coming off. It does sometimes leave a residue, especially if it wasn't heated enough. But that's better for me than anything removed.
