Conky with a bash script

Question

I am trying to change the color of my CPU temp text in conky to green, yellow or red based on the CPU temp.  I am getting this in my conky:
Temperature:  color green33
Here is my conky line:
${voffset 1}${goto 40}Temperature: ${font Droid Sans:style=Bold:size=8}${execpi 120 sensors | grep Core0 | paste -s | cut -c15-18 | xargs ~/.conky/colorize.sh}${hwmon 0 temp 1}°C${color}${font}${alignr}
Here is my bash script:
#!/bin/bash
# colorize.sh
COOL=65
WARM=80
if [[ $1 < $COOL ]];
then
echo "color green"
elif [[ $1 > $WARM ]];
then
echo "color red"
else
echo "color yellow"
fi
exit 0
Any help would be greatly appreciated.
Thanks

Using exec(p)(i) makes your conky run heavier, so, why wouldn't you use the built-in conky variables to achieve the same...
I'm using: (before "TEXT")
template2 ${color2}${if_match ${hwmon \1 temp \2}>75}${color orange}${if_match ${hwmon \1 temp \2}>90}${color red}${endif}${endif}${hwmon \1 temp \2}${color1}
and i call them like: (after "TEXT")
Temp ${template2 0 1}/${template2 1 1}/${template2 2 2}/${template2 2 4}
Of course you need to find out what numbers you need to pass to hwmon...
