For color between the lines you can look at the 
-rarea- twoway graph. See the example below. For
labels in the colored areas you can look at the 
text option, see: -help added text options-

*------------------- begin example ------------
sysuse nlsw88, clear
recode age 46 = 45
gen byr = 1988 - age
gen lths = grade < 12 if grade < .
gen hs = grade == 12 if grade < .
gen sc = grade > 12 & grade < 16 if grade < .
gen com = grade >= 16 if grade < .
collapse (mean) lths hs sc com, by(byr)
gen zero = 0
gen tillhs = lths + hs
gen tillsc = tillhs + sc
gen one = 1

twoway rarea zero lths byr     ||         /*
   */  rarea lths tillhs byr   ||         /*
   */  rarea tillhs tillsc byr ||         /*
   */  rarea tillsc one byr,              /*
   */  xlab(1944(2)1954)                  /*
   */  xscale(range(1943 1954))           /*
   */  xtitle("year of birth")            /*
   */  ytitle("proportion")               /*
   */  title("distribution of education") /*
   */  plotr(m(zero))                     /*
   */  legend(order(4 3 2 1)              /*
   */         label(1 "less then"         /*
              */      "high school"  )    /*
   */         label(2 "high school"  )    /*
   */         label(3 "some college" )    /*
   */         label(4 "college"           /*
              */      "or more"      )    /*
   */  )

Hope this helps,
