Were they *always* brown? Age-related yellowing of the eye's lens could be a factor.
Not in my case - I've owned RL01 packs since I was 19. I thought they
looked dark brown then and look dark brown now.
And I know (i.e., have been tested) I am not colorblind.
It's also possible that since I run them at home (under incandescent
light and sunlight) and some may have only seen them in data centers
(cool white florescent) there's a perception difference based on input
spectrum.
Surely someone here owns a vintage spectrophotometer,
or at least a camera and
grey card.
I do not own a spectrophotometer, but a gray card wouldn't be hard to score.
