Unusual use of blue pigment found in ancient mummy portraits

No blue is visible to the naked eye in the paintings, but when the researchers used analytical tools for an in-depth study, they discovered the ancient artists used the pigment as material for underdrawings and for modulating color — a finding never before documented.
