I finally found out the problem. It is the default pdf viewer on my phone that is defective. I changed to a different pdf viewer and the problem resolved. Thank you for taking out the time to help me.

last time I checked I didn't have any kind of Daltonism. That page, however, didn't look fine to me it had a yellowish background to it. I am curious about the origin of those background artifacts at which point of the scanning or ocring does it happen?

Well I tend to read books on my phone so I cannot 'right click' the pdf link. I would really be grateful to you if you could suggest a solution that works for my phone. Attached is a snapshot of the book as it appears before me on my phone.
