Pick colours from an image

[awaisamjad]

Are there plans to add a feature to extract colours from images?

Example

pastel extract <image> -n 5 which would return the 5 most present colours in the image.

Thank you

Interesting idea.

the 5 most present colours

How does this work? If there is a large patch of different oranges, and a smaller patch of blues in an image, how do we make sure to get both blue and orange... and not just five different oranges?

Principal component analysis? Or something similar?

pywal does this btw.
It has multiple backends, perhaps pastel could use the same backends.
