One of the nice things I found with AI was that some images seemed to have well-matched to colors. Intuitively, I wanted to derive the color palette from the image, so I found a tool through Google and settled on the best colors.

There was no difference this time and I decided to use the following image for the background.

The next step was to find a page which can extract colors from images. Just google for “extract color palette from image” and you will get plenty of results. I usually use the same one, but this time I was wondering if a different page would give the same or not.

At least some colors were suggested more than once:
