pinkish/greenish/yellowish gradient on all tapes
 

my hands were too fast...

hello everyone,

i've captured all of my family's tapes and there appears to be a pinkish/greenish gradient layered upon the whole tapes. it's particularly visible where there are whites.

below you can find a couple of frames where the issue is evident.

i don't know what you call it or what the issue is exactly, but i would love to know how to fix it.

can it be corrected while capturing?
can it be fixed via software e.g. color correction?
was it a dirty lense when the videos where recorded in the first place?

i captured all tapes in huffyuv.

i'd appreciate any direction you can point me to.
