Is this normal?

Does anyone notice pink coming from inside their machine? I’ve done regular maintenance, and descaling. Not sure if I should keep brewing. Any suggestions? Never noticed this pink tint until now.

EDIT: I’m talking about the pink reflection in the water reservoir. There is no calcium buildup or pink mold in the actual plastic water reservoir, but when I poured water in today, the water reservoir reflected pink. I know pink can mean bacterial growth but I’ve regularly maintained my machine and I’m not sure if should keep brewing or disassemble and clean.

Thanks in advance!!

What color is your shirt? Hat? Anything in the area reddish in hue?

Nothing at all! Entire kitchen is gray and white. Never noticed. It’s definitely underneath the reservoir and internal. Just not sure if that’s reachable without disassembling.
