This GIMP (GNU) tutorial demonstrates how to create a Smooth Vivid Pattern using GIMP’s Blend Tool and the Wave Filter.
You can quickly Undo a step at any time by pressing Ctrl then Z. Alternatively, click a previous Undo History snapshot - Windows then Dockable Dialogues then click Undo History. In addition, to Zoom in (or Zoom out) of your image; from the top menu, choose View then select a Zoom Tool from the subsequent drop-down list.
Ensure the Layers and the Undo History Palettes are visible, and then drag them into position over your workspace - (Windows then Dockable Dialogues - then click Layers and Undo History).
Launch GIMP & Organise Its Workspace & Palettes
Create a New (Transparent) Image, and set the following Width and Height and Fill with Transparency attributes. (Alternatively, set New Image dimensions of your choice).
Now, set the Foreground and Background Colour Swatches to the colours of your choice.
Then from the left-side Toolbox, activate the Blend Tool.
Then (from the Blend Tool’s left-side Options Box), click open the Gradient tab; and from the subsequent drop-down library, activate a Gradient of your choice. I am selecting the following FB to BG (RGB).
Now, Ctrl-click a Gradient Line in the following direction.
Then from the top menu, choose Filters then choose Distorts and then choose Waves. And from the subsequent Waves dialogue box, enter the following settings, or experiment, and then click OK.
