Question about changing thread colors
I want to change the colors in a design to another color pallet and wondered if there was a program or site that lets a person put in the original colors and get a match in tone and color in a different color. I am not sure this makes sense but as an example I have a cat design that is in yellows and I want to have it in shades of gray. Or a flower in one color and I want to change it to another color pallet.
Thanks for any help!
