as you say this program is a bit web-centric but...
i bought this this program to generate color scheme palettes to 'paint' virtual houses on a virtual site.
i use it with Paint Shop Pro (old version

so please dont 'drop' the PAL palette.
i showed it to my sister who knows zero about computers/the web and she immediately started trying to
generate colors to decorate her (real) house. she fiddled for ages and eventualy printed them out, she'll probably go down the shops now and try to find the matching paint!! maybe you can get dulux to sponsor you, link to their site to buy paints!!
also her hobby is (real)painting so she was trying to generate colors for this too, but they seem to use a subtractive RYB color model and i dont know if this translates easily or at all. RGB->RYB ?? dont know.
i also do a bit of web-site design so i use it for that too, but i bought it more for the above reasons.
this is a very good program, and i (and my sister) enjoy using it. thankyou very much. oh, one thing.
we built up a palette (for my sister living room), then she said: is there any way to find out if this color
goes with what we've already got? interesting question. no idea how you would implement that.
maybe:-
1. you have made a palette and it is selected.
2. in the palette builder, you select option to match current palette
3. you select a colour
4. you show the closest match of that color to current palette, and allow add
dont know. may complicate things too much. just an idea.
anyway my sister wants a computer now just so she can get this program to play with.
