Description: Original concept recreated by filteringSuch a filter is built up by two parts first generating a basic textureOriginal image looked way similar to a turbulencefractal noise however it turns out it is a tad bit different lookingThe other part is mapping a colour gradient to the textures luminance levelsTheoretically that is a pretty straightforward thing to achieve however there are some problems with itFirst and foremost the shallow colour depth how it is rendered resulting in banding even more than present on the original imageBlurring may be used but I rather not have included that in the filter chainOther problems with gradient mapping are somewhat can be handledIt is achieved by a component transfer filter primitive that uses table inputs on the rgb channels That means you are strict to represent a gradient where each step is in equal distances The one used on this image consists of 26 steps visible larger steps needed to be covered by more steps of the similar length Matching a custom gradient with that model is a quite tedious process with trial and error
