Happy New Year to you too!

Ahhh, indeed, you are in the epicenter of early colour photography; Luis Ducos du Hauron, Gabriel Lippmann, the Lumiere brothers...

I'm jealous!

You know, someone proposed the idea of interference colour photography early on; Bequerel maybe?? (IDK off the top of my head) Anyways, it'd be neat to read the original disclosure.
