In Affinity Photo, when creating a  i.e. 12 colors palette from an image, how is the color calculated?
- is it how many pixels from that color in the image?
- are than the 12 colors placed in the palette in decreasing order? The first being the one of the most pixels in the image?

If not, how are colors picked statistically and how are they ordered in the palette sequence?

Thank you for explaining this: I need to be able to compare palettes from one painting to another...

The process uses the octree color quantization algorithm as part of our raster engine and believe it's ordered by the pixel order. Here's an example of something similar showing the process.

I find the color palette generation in Designer quite weird. If I create a vector image with a few colors and then let AD create the palette from it, I end up with colors I never used. Does it use the pixel version of the image (with anti-aliasing edges) to generate the palette?
