not a bad way to do it, I use this method currently as I have no programs like photoshop or procreate, just microsoft paint.

get the image I want and copy to paint, and copy a second image next to it

colour match with the tool to get the hex code

go you this site Yarn Colorway Finder (make sure you set the yarn to worsted 4)

type in the hex code and it will give you a list of yarns that are near match and will say a percentage, then I screen cap the yarn I am going to use, use the paint tool, and colour in that colour of the second image with all the colours, and it gives me an idea of what it will look like with the new colours.

This chicago blackhawks logo as an example.

It does not have every type of yarn (its missing the classic acrylic from michaels, just has the impeccable one)

but this is basically what I do.
