Color of growth media for CRL-6475
My cells (ATCC® CRL-6475 ™) have been in culture over the weekend with the correct culture media, why does the media appear black today?

The cells produce melanin causing the culture medium to appear dark brown or black, especially when approaching a high level of confluence.
