My submission for the Mother Nature weekly challenge.
Thank you very much. I did have an issue with the palette and was inadvertedly using extra colors when I originally posted this. I thought I'd fixed it since the tool on this site is showing me 11 colors. Is it still showing you 12 colors? Are you using the same tool? By the way do you know of a good image analysis tool I can use locally before uploading to avoid this issue in the future?
Once again, thank you so much for the feedback, greatly appreciated.
According to the image spec tool, this has 12 colours.
Keep in mind that transparency counts as a colour too.
