I have an icon that consists of a blue ball with a light effect on it. The
light effect creates various shades of that ball's uniform color.

The edge of the ball is blurred and has an alpha channel that mixes the shaded color to the background color (whatever that is).

What I would like to do now is change the base color of that ball to green.

I would generally use the Hue-Saturation tool for this (in Layer/Colors menu). Turn the 'Hue' slider to the left until it's sufficiently green.

You might also try the 'Colorize' tool in the same menu.

I know this has been asked before and I have tried several of the proposed solutions but all to no avail.

I tried colormap rotation, curves, indexes, etc etc. I need more help being a VERY BIG newbie on the gimp.

I am using 2.0 pre 4

Layers->Colors->Hue & Saturation, change Hue. If this doesn't work, just use the selection tools for letting off the parts you don't want to be affected by the hue change.

Or, filters->colors->channel mixer. If this doesn't work as you desire, just use the selection tools for letting off the parts you don't want to be affected by the hue change.

And yes, please...upgrade your GIMP when you can. :-)
