Hello,

this may be one for GrADS developers:

Is it possible to create "transparent" colours in GrADS?

The idea came about wanting to show anomaly charts
for consecutive time periods to express an element
of persistence in the anomaly.

In some areas, multiple time steps would overlay, showing the brightest
colours with the most persistence, in other areas the
hue would be more pastel, indicating a transient anomaly.

How can this plot be achieved?

Best regards,
Bernd.
