My answer ... "I am coloring this, but I want to color this ... if I can find the artist first."
I am sure she thought I was crazy. Here is why I answered the way I did.
1. I want to support artists, not just color whatever I find on the Internet.
2. I wouldn't want someone to rip me off.
3. I dropped a piece of wisdom -- don't rip off artists! (Not that my friend does!)
So Zombie Girls there .. yeah, I love her. She is way more detailed than most things I color. I find her to be a challenge. I find her to be fun. I find her shared in way, way too many free coloring whatnots.
Pinterest and Google Searching are not the only culprits of hosting stolen art. There are plenty of "Free Coloring Book Sites" full of art that probably shouldn't be there. If you can't find the artist's name there is probably a reason why it is hidden.
Best Practice: Try to find the artist.
Here is a simple thing you can do to try and find the artist.
Right click the image and go to "Search Google for Image"
You will get a result looking like this:
Scroll through the results and see if you can find something that might lead you to the artist. I found an interview with Deborah Mueller the Chubby Mermaid. In that interview it linked to her Etsy Shop where I found ...
Here is where you would want to buy the coloring book so that you can color the page. If you wanted to you could reach out to the artist and tell her what you found online and where - maybe even give a link where you found it. I know that I would want to know if you found my art shared illegally somewhere.
This search took me less than 5 minutes. The interview was on page 3 of the search. Yes, it took longer than Right Click, Save, Print. I can feel good about coloring this page because I did my small part on the war against theft. Plus, when I make a purchase I will be supporting the artist.
I realize there are so many worse things out there in the world but this is just a small thing we could all do to support coloring fans and the artists that keep trying to bring you what you love.
