I am wondering how the woman's writing hand is oddly coloured and so much greener than her tint tone on the other hand? Does it have to do with the circuit boards around her writing hand or the temperature of the room? If possible, can you give some optics points of view as well?

Thank you so much.

  • \$\begingroup\$ In case anybody's wondering: Those cabinets behind her look like analog computers, and those "trays" on the table with masses of wires on them... Those are the programs for the computer. They're called "plugboards" en.wikipedia.org/wiki/Plugboard \$\endgroup\$ Dec 5, 2021 at 21:05

Possibly some kind of color quantization during the digital history of this picture. It's not only the hand, her jacket also suffers from a color problem and there are plenty of completely white pixels. Her face isn't that clean either, and there is this reddish mark from her ear to her throat that should have been a delicate shadow.

Many of these old pictures have had a past as a GIF later re-encoded as a heavily compressed JPEG (storage wasn't cheap, and screens were small).
