the {n…n} glob pattern does not work outside of zsh

not all methods and paramters were controlled

after my 1 year break in which I can not overview
the changes I try to set a new start

rename contrasts module to views
create contrasts module
convert luminance function to method of LightDark Class
modify compose method to work with contrast module

just as a reference implementation for the value contrast and not generacilly

so that it is not accessible by the instance

reference implementation for Movie, Frames class
scatterplot contrast without plot as function in contrasts module
helper functions in helpers module
