With 6000+ gradients that is easier said than done.  

The site has, presently, a set of "selections" (blues, topo, bath and so on) 
which myself and Etienne have discussed as forming the basis for such
QGIS sets (outline - XML file of gradient paths used to generate the
cpt-city 
pages and also to be downloadable, these could then be used to filter the 
GUI, or to make specialist sub-sets of zipfiles on the QGIS side).  That we
will have a look at after the zip download is tested and working.

As to the GUI navigation of such a large number of gradients, that is a
challenge.  I personally use the site itself as a selector, then when I find
the one I want, I copy-paste the path (which is listed under the preview
on each individual gradient's page, for exactly this purpose) into my
script.

eg on

 
http://soliton.vm.bytemark.co.uk/pub/cpt-city/bhw/bhw4/tn/bhw4_003.png.index.html

the path is

  cpt-city/bhw/bhw4/bhw4_003

I've not had time to look at the QGIS selecter, if it does not have a 
"gradient path" input (ie, no extension, no base directory) then perhaps
it would be an idea to add one.
