Yes, of course. I was just curious. But in the meantime many have
reported using red safelights, so the answer's not that relevant.
I dug back into my records, and found that I bought an OB (amber) and
3 (dark green, for panchro) safelight filter for the school darkroom
on 19 May 1965. No mention of a red filter yet. And
https://www.kodak.com/content/products-brochures/Film/Safelight-Recommendations.pdf
agrees with me that amber is the most appropriate colour for black and
white print paper. I wonder why red safelights were so prevalent.
