I have drawn thousands of single-panel comics over the last 11 years. They are mostly on evaluation related topics, but I also touch on topics related to research, data visualization, entrepreneurship, and design).

Just about every blog post I share on freshspectrum includes at least one cartoon. Some include lots. Outside of this blog, you’ll also find my cartoons in other people’s presentations, books, blog posts, and on office walls worldwide.

About those cartoons, umm, can I use one in a…

So I creative commons license all of my cartoons. So yes, you can use them.

This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.

How do I attribute?

Technically I only require that you keep the “freshspectrum” signature on the cartoon. But I do appreciate links back to my website. So my preferred attribution would be something like this…

“Comic by Chris Lysy of freshspectrum.com

And if you do use that line, please also link to my main website.

This site is called Evaluation Comics, but the cartoons are signed freshspectrum, what’s the deal?

This Evaluation Comics site is a freshspectrum spinoff. For over a decade I signed my cartoons as freshspectrum hoping to inspire people to visit my blog. And now that freshspectrum information design is my business, not just my blog, why stop now?

There will always be a comics link on freshspectrum that bring visitors to this site.

But what if it’s commercial?

The way to get royalty-free commercial use is to join the freshspectrum Patreon community at the Partner tier. You only have to pay more if you make me read and sign legal documents (I hate reading and signing legal documents).

Where do I read your cartoons?

Here on this site! I post new cartoons on Mondays, Wednesdays, and Thursdays. You’ll also find cartoons on my blog > freshspectrum. At the very least you will find the last 6 months of cartoons publicly available.

I want to read them all!

Join us in the freshspectrum Patreon community. Join at any level and you get to immediately unlock the archive here on this site. I’m currently working on bringing over just about my entire backlog of single-panel comics.

That said there will always be some cartoons that fall through the cracks, or that never end up going public. And even though they will never make it to this site, they will exist inside my private dropbox folder, available to patrons at the $5 presenter level or above.


Do you have a book?

I have one cartoon book (Evaluation Illustrated), it’s filled with over a hundred audience favorites. You’ll find it on Amazon and some other booksellers.
