Create beautiful gel prints
without guessing what color 
comes next.
Finally understand how your paints behave on the gel plate. No color theory needed.
 
 
Learn how layering color creates beautiful, harmonious prints—through simple experimentation and play.

A Common Frustration, 
a Surprising Discovery
 
I’ve seen it again and again in the studio—someone picks colors they love, rolls out their first few layers, and then… disappointment.
They print a light transparent color over something darker, expecting it to pop. Instead, it disappears. The contrast is gone. The excitement fades.

Most people think they’re doing something “wrong.” They ask:

Should I be printing light to dark?
Is there a rule I don’t know?
Why does this color look totally different now?

Here’s the truth:
There’s no single right order. But there is a system that helps you uncover how your paints behave—and how to use that knowledge to create beautiful surprises on purpose.

If you've ever wished you could peek inside your paints' potential, this is your Pandora moment.





Introducing Pandora’s Palette: 
A Two-Part Journey in Layered 
Color Discovery
 
This two-part online, self-paced course invites you to follow your curiosity, explore unexpected outcomes, and unlock the hidden magic inside the colors you already have—without getting bogged down in color theory.

If you’ve ever wanted to feel more in control of your color results—without giving up spontaneity—Pandora’s Palette is for you.

What You'll Get...

Essentials (Part 1)


You’ll create your own personalized color reference—using the paints you already own—to see how different layering orders change your results.

  • Step-by-step video lessons—easy to follow, even if you’re new to gel printing 
  • My 3-print registration system makes layering easier, faster, and more consistent 
  • Printable worksheets guide your printing process—no need to rewatch videos every time you test a new color combo 
  • A color-tracking spreadsheet where you can log your paints and note unique characteristics as you print 
  • Supportive student community—share your prints, ask questions, and connect inside the course and on our private Facebook page 
By the end of Essentials, you’ll have your own printed key to the “Pandora box” of your paints—a color guide that reveals their true behavior when layered.

Master Class (Part 2)


You’ll learn how to make advanced prints that are both layered and composed—with a little help from masks, stencils, and a few clever tricks.

  • Advanced demos that build directly on what you learned in Essentials 
  • Tips for designing stencils and masks that pull your composition together 
  • Clever tools for simplifying decisions about contrast, opacity, and layout 
  • A DIY color aid to help you choose paint pen embellishments with confidence 
  • Continued access to the private Facebook group—share your progress, ask questions, and stay inspired alongside other students 
Master Class is where everything clicks: your curiosity becomes creation, and your prints come alive with layers of meaning and surprise. (Over 4 hours of video.)


Who This Course Is (and Isn’t) For
Diana Garrison

Pandora’s Palette is for you if:

  • You love working with color but wish you understood your paints better
  • You’re curious about how layering changes results—and want a system that shows you
  • You’re a playful experimenter who appreciates structure (but not rules)
  • You want to create more intentional, beautiful gel prints using what you already have

This might not be for you if:

  • You’re looking for a traditional color theory course
  • You want fast, formulaic “use these three colors” answers
  • You’re not interested in experimenting or learning through hands-on play
  • You don’t enjoy printing in multiple layers

Frequently Asked Questions
How much experience do I need?
Beginners are absolutely welcome! If you’ve done a little gel printing before—even just some casual experimenting—you’ll be right at home. I highly recommend spending some time playing with your gel plate before you begin. The more comfortable you are with the basics, the more fun you’ll have following your curiosity through the course. You don’t need to be ‘good at color’ to succeed here.

What supplies will I need?
You’ll need basic gel printing supplies: a gel plate, brayer, acrylic paints, and paper. That’s it to get started!
A full supply list for Essentials is available here.
The supply list for Master Class will be included inside the course.

Are the videos captioned?
Yes! All videos include English captions and transcripts to support different learning styles. You can also pause, rewatch, or slow down the pace as needed.

Do I need to have taken any of your other courses first?
Nope! Pandora’s Palette Part Essentials is designed to be a fresh start. If you’re new to gel printing or just want a deeper understanding of your paints, you’re in the right place. That said, I recommend spending some time playing with your gel plate before you begin.

A little about me
 
A day-long professional development class for art teachers during the summer of 2020 got me hooked on gel printing from the get-go! It was the summer of Covid; I barely left the house and couldn't make prints fast enough!

Over time I have developed my own techniques, and I'm happy to pass them on to you. I recently retired after 21 years of teaching children so I can spend more time on my art and on teaching those who are truly passionate about creating.

I hope you'll join me. There's more to come!
