I am trying to change an Image that has a ComponentSampleModel that has one band (its a float 0.0 - 100.0) into an RGB. I would like to define a color ramp to accomplish this but I am still trying to become familiar with the concept.

If I had the color ramp:

0.0 - green

50.0 - brown

100.0 - grey

Is there a way to convert my single banded image into an RGB using the above ramp?

Thanks in advance!
