[Frameworks] Color separation experiment

[Albert Alcoz]

Hello John,

Some other films that could be interesting for the color separation
experiment are *Colour Separation* by Chris Welsby
<https://lightcone.org/en/film-1532-colour-separation> and, as Eric Theise
suggested, Tomonari Nishikawa's *45 7 Broadway*
<https://vimeo.com/117525190>.

In 2015 I did an Ektachrome reversal super 8 film playing with different
colour filters. It was a freestyle procedure though and here are some
frames of the outcome: *Color Spectrum
<http://www.albertalcoz.com/2015/05/espectro-cromatico.html>*.

Best,
Albert
