The other way around.

No, that's why you use yellow orange or red filters on modern panchromatic films to reduce the lights blue content, to bring out the clouds.

No, you said orthochromatic films were more sensitive to red and pan film were oversensitive to blue- As we know ortho films are sensitive to blue and green (thus can be developed under red light) and pan films are sensive to all colours, certainly they are red sensitive.

It was because as you write it was to give it it's full title Kodak Verichrome Panchromatic ( sensitive to all colours, although in fact it was oversensitive to blue light) previously most monochrome films were orthochromatic (more sensitive to red ). Unfortunately I'm old enough to have used it

The original Verichrome was not panchromatic, it was orthochromatic.

Kodacolor was originally associated with an early lenticular (additive color) color motion picture process, first introduced in 1928 for 16mm film.

Just wanted to show that those names, clearly, do not come from that typically base. I'm sorry if I did not explain it right.

I see. But I was thinking of more historic film names, before our period so to say. There you got a lot of names derived from Greek or Latin.
