That worked :) Thanks, Adam.

| Hi Nicole,

| setup, gray80 is not present, although gray50 is:
|
| gsn_define_colormap(wsplot,"BlWhRe") ; sets your colormap to
| BlWhRe
| gsn_reverse_colormap(wsplot)
| newc1 = NhlNewColor(wsplot,0.5,0.5,0.5) ; adds gray50 to the
| colormap
| newc2 = NhlNewColor(wsplot,0,0,0) ; adds black to colormap
| newc3 = NhlNewColor(wsplot,0.5,0.5,0.5)
|
| The newc2 and newc3 lines aren't necessary, as they add black (already
| present in the BlWhRe colormap) and again add gray50.
|
| When you request a color that isn't in your colormap, NCL will try to
| choose the color that it thinks is closest to the one you want. In this
| case when you requested gray80 it chose a light red.
|
| Try setting this:
| newc2 = NhlNewColor(wsplot,.8,.8,.8)
|
| and I bet the vectors will get colored correctly..
| Hope that helps..
