At the moment it's "probably" Linux-only, but that's because I 
only wanted a proof of concept and I worked on it on my Linux 
installation. I imported this library/Dub package 
https://github.com/yamadapc/d-colorize and just used it. Which, 
by the way, it's no-good at the moment since I saw that Dub 
doesn't use Dub packages itself - probably because, otherwise, 
you don't have a way to easily compile it without Dub itself, I 
guess :P so I'll need to either write my custom color outputting 
code within Dub's source or just import that library.

Of course making it cross-platform is a mandatory thing to me. 
Windows also needs some specific stuff to output colors, as you 
can see in the library I linked, so there are definitely some 
things to do to support all the platforms. I may even take a look 
at how DMD itself outputs colored output, I guess it will be nice 
to keeps things consistent.

As for MacOS having a different background... I don't really own 
a Mac nor I have ever used one before, so I don't even know how 
tools usually output their colored text on it. At the moment it 
just sets the foreground color to green/yellow/blue/whatever, 
without changing the background, if that was your concern. If you 
meant that yellow-on-white is not readable... well... I guess so. 
Maybe two different color palettes should be used? IDK, as I said 
I never used a Mac before so I don't really know how other tools 
handle this, maybe if some Mac user could help on this, it would 
be great.

Thanks for the appreciation by the way!
