Quick and dirty colour picker for Copic markers.
The JSON data for colours were nabbed from https://www.swatchtool.com/copic.
Type an RGB value into the input field, e.g.
123,200,65 or #ff08a2 and select a colour space
(RGB, HSV, Lab); the Euclidean difference between each Copic colour
and the input value will be selected and used to compute a weighted
difference (or similarity), and the table sorted accordingly.
(Weighted: an extremely crude calculation of max differences;
may not make sense in every colour space.)
The code is awful. This is a quick and dirty tool just to, well, pick out marker colours, not set up a long-term software project.
