On the examples you posted, it looks like they are finished thusly:
The green strat looks like they've done a green dye on the quilt top, then sprayed the black with black gloss toner, bursted that over and finished with clear high gloss top coats.
The blue strat looks like they did a blue dye - I'm still working out how to do the "washed out" piece - then sprayed the back/burst over with "candy blue" and high gloss top coats.
The blue Tele doesn't look dyed at all; they left the quilt natural, sprayed the back/burstover "candy blue" then high gloss top coats.
If you can find the right colors you want, the Woodburst transparent color stains work real well, and so far it appears that unlike many sites, their color chart on the web is dead on accurate: http://woodburst.com/colors.html
As to toner, I reallly like the Mohawk Ultra Classic toners - CB sent me some leftovers I'm doing the cherry burst finish on my Thinline with, but I just checked their website and besides their color chart being way off, they only offer colors in wood tone hues, so no blues/greens; maybe CB or somebody else can recommend some vendors for other toner colors.
