I want to know what software is offered in Ubuntu Mate's Boutique without downloading Ubuntu Mate 18.04.
How can I do so?
The reason is to settle a doubt about the availability of the gcolor2 package.
As the image below shows, it is absent from the regular Bionic repositories:

Furthermore Debian removed gcolor2 according to RM: gcolor2 -- ROM; RoM, RoQA, dead-upstream, unmaintained, better alternatives available dated Fri, 21 Jul 2017 05:12:02 UTC well before Bionic was released (26 April 2018).
Could it perhaps somehow be offered via Ubuntu Mate's Software Boutique? The Software Boutique is described here as
An easy-to-use software distribution program for Ubuntu MATE. The team curates a selection of tried & tested applications that integrate well with the Ubuntu MATE desktop.
sudo snap install software-boutique --classic
to get its user-friendly interface. – N0rbert Oct 09 '19 at 20:25
