Related to colors on UI, since I have been working on an updated fork of Chroma.js; have found an easy way to know which color is associated to an element in menus (without requiring to open the color picker).
Thanks to Name that color and the new chroma fork, I can show a name for the color in the entry (the most prox. color).

Which should give you at least a hint of the current settings on menus. 'None' in the case of the previous button discussion equals to 'no button color and border'.
Will implement this to all my scripts. In case someone more is interested, it just requires 3 lines of code:
include('ntc.js');
const Chroma = require('chroma-ultra-light.min');
const getColorName = (val) => {return (val !== -1 ? ntc.name(Chroma(val).hex())[1] : '-none-');}
For the require:
let module = {}, exports = {};
module.exports = null;
function require(script) { // Must be path relative to this file, not the parent one; add RegExp if needed
include(script + '.js');
return module.exports;
}
