I’ve created a palette in photoshop. The file is 1x256 pixels saved as an index color png. When I load the image, or choose Colors/load palette and select the image, I get the colors, but not in the order they exist in the image. So all my ramps are dispersed randomly throughout the palette. How do I get the colors in the palette to appear in the same order as they are in the image?
Please go to the palette editor window. Then go to the area where you can arrange colors etc.:
Hit Ctrl + A or use the right mouse button context menu within the color palette slots to select all colors. Then in the context menu use “Sort/Sort by Appearance”.
This just goes through the image and uses the ordering as colors appear in the image. Repeating colors are skipped.
