Linoleum discoloring to a purple - any idea why?

In the basement utility room we have linoleum over the unfinished cement floor. A while back we had a small leak in the basement, some water got around the now discolored area (likely under as well).

Not sure if what we're looking at is mold or just the result of some of the moisture?

Attached a link with a bunch of pics of the top of the linoleum and lifted a corner of it and took a few pics below.


Will likely have someone inspect it, but wondering if anyone can shed some light on this.

Sounds like mold growth. Floor was probably laid using mastic. That’s a great feeding ground for mold, especially if applied directly to a concrete slab (moisture wicking up through the concrete).
