I wanted to use a 3-bit palette in Gimp. Why? To preview images for Nokia Sleeping Screen.
Gimp does not have a 3-bit palette by default. But it has a nice feature where you can add your own palette. So I created one.
Start the Palette Dialogue with Windows -> Dockable Dialogs -> Palettes
You'll see this box:
You'll see this box now:
Save this image and open in Gimp:
I found this image on a Wikipedia article. This shows the 3-bit palette.
Now click on the 8 colours in the image you opened in the previous step. You'll see the colours filling up in the 'New Palette' window. Give a name to the palette so that you can identify easily:
Click the save symbol.
Well, thats it. You have a 3-bit palette now!
Okay, so how do I use it?
I'll describe it in the next blog when I show how I created images for Nokis Sleeping Screen.
For short instructions:
Image -> Mode -> Indexed
Click Use Custom Palette
Click the colour symbol below this and select 3 bit colour palette
Select a Dithering option
