Missing: 'awk', 'sed' and 'coreugils'.
The colorscript.sh needs some ‘absolutification’, e.g. using 'substitute*',
to refer to awk, sed, tr, wc ... by their absolute path instead of using
whatever is in the profile.

Some script in ‘colorscripts’ may need changes as well

"; MIT" isn't necessary, as license:expat is unambigious,
whereas MIT is sometimes used for the X11 license and can theoretically
refer to any license ever used by MIT.  (Though in practice ‘the MIT license’
either refers to the X11 or the expat license.)
