Error on color bar

Dear Ncl users,

I am trying to build a personnal colorbar using an NCL
exemple.

colors = (/ (/217,255,217/), (/163,255,163/),
(/106,255,106/),(/43,255,106/), (/0,224,0/),
(/0,134,0/),(/255,255,0/), (/255,127,0/)/) * 1.0

colors = colors/255.

But i get the following error

fatal:CvtStringToCmap:Unable to convert string
"colors" to ColorMap
warning:Error retrieving resource wkColorMap from args
- Ignoring Arg

Any adea to resolve this?

Thanks
