quick response to the first part.
   92   colors = where(((rf.ge.0.1).and.(rf.lt.2.5)),"Blue","   ")  ; This
is a string variable
   93   colors = where(((rf.ge.2.5).and.(rf.lt.7.5)),"Red","   ")   ;;;
This will undo anything set in the line above.


Quick edit below:

colors = new( dimsizes(rf), string)
colors = ""  ; not really necessary.

colors = where(((rf.ge.0.1).and.(rf.lt.2.5)),"Blue",colors)
colors = where(((rf.ge.2.5).and.(rf.lt.7.5)),"Red",colors)  ;;; now
anything set on the first line won't be unset on this line. continue
as necessary.
colors = where(((rf.ge.7.5).and.(rf.lt.15.5)),"Yellow", colors)

print(rf+"     "+ colors)   ;;;  look at your data and the output to check
it worked.

;; colorss= stringtoint(colors)    ;; This won't work and shouldn't be
needed.  You'd want something like:
