Maybe the following is what you want? See -help extended_fcn- and 
-help tokenize- for more details.

*----------- begin example ---------------
clear
local colors "red blue yellow"
local n : word count `colors'
set obs `n'
gen colors = ""
tokenize `colors'
forvalues i = 1/`n' {
	replace colors = "``i''" in `i'
}
*----------- end example -----------------
(For more on how to use examples I sent to the Statalist, see
http://home.fsw.vu.nl/m.buis/stata/exampleFAQ.html ) 

Hope this helps,
Maarten
