coloured clouds, how to?

I am trying to recreate an effect from another photo editing application and I am wondering if there is a better way to achieve the cloud effect I'm looking for.

I'm using "Filters, Render, Clouds, Solid Noise" to generate the clouds. Unfortunately that only generates black and white clouds whereas the other software generates clouds using the current background and foreground colours. Is there a way to do this that just have not discovered or do I have to colour the clouds afterwards?

I'm getting some adequate results using 'Layers, Colours, Colourize' but I was hoping some one might be able to recommend alternative or better approaches.

Sincerely

Alan Horkan

You can apply all gradients (e.g. the FG->BG Gradient) via Filters->Colors->Map->Gradient Map.

I also have a script that does the same, but applies a palette instead of a gradient. You can make a palette of your image's colormap, and use it if that is really what you want. I have palette sorting too.

Hi,

Quoting Alan Horkan :

I'm using "Filters, Render, Clouds, Solid Noise" to generate the clouds. Unfortunately that only generates black and white clouds whereas the other software generates clouds using the current background and foreground colours. Is there a way to do this that just have not discovered or do I have to colour the clouds afterwards?

You have to colour them afterwards, as far as I know.

I'm getting some adequate results using 'Layers, Colours, Colourize' but I was hoping some one might be able to recommend alternative or better approaches.

Map to gradient (Filters->Colors->Map->Gradient Map) should give you the result you're looking for with the default BG - FG gradient.

Or you could try the Misc tab of the colormap rotation filter (Filters->Colors->Map->Colormap rotation) and select a big swarth of grey values (changing the "What is grey?" value) and map them to the FG color (or whatever color you want).

Cheers, Dave.
