Polymer Clay Color Recipes | Autumn Brew

Fall has arrived and along with it, spiced beverage season. Now that the sandals have been put away, it’s time to bring out your scarves and and cozy sweaters and contemplate which overpriced seasonal latte best matches your aesthetic. (It’s the one with the whipped cream mountain and a sprinkle of cinnamon.)

This Autumn Brew palette is inspired by the golden hour glow of October afternoons, the soft clink of a ceramic mug on a wood table, and the deeply spiritual act of ordering a pumpkin spice anything. It’s cozy, nostalgic, and has just the right amount of warmth.

With warm neutrals, baked pumpkin tones, and a deep spiced base, these five polymer clay color recipes are perfect for earrings, pendants, trinket dishes, or whatever fall-themed magic you’re conjuring at your workbench.

A Quick Tip on Mixing

When I share polymer clay color recipes, I use parts to measure the ratios. You can grab whatever cutter you like, just stick with the same one and keep your clay thickness consistent for every color in the recipe.

A visual guide showing how to divide a square into fractional parts for measuring polymer clay color recipes. The top row shows a full square labeled "1 part," then a diagonal half labeled "1/2 part," and a quarter triangle labeled "1/4 part." The bottom row continues with smaller fractions: one-eighth, one-sixteenth, and one-thirty-second of the square, each represented by increasingly smaller triangles within a grid. All sections are shaded peach pink for clarity.

Personally, I prefer to use squares. They’re super handy for slicing into smaller portions, and if you cut corner to corner, it’s accurate enough even for those of us who couldn’t eyeball a measurement if our lives depended on it. Seriously, I’m terrible at eyeballing, so I’m all for keeping it foolproof!

Tools & Materials

To recreate this dreamy palette, you’ll need:

Fimo Professional polymer clay in these colors:
- True Magenta
- True Red
- True Yellow
- True Blue
- White
- Black
Pasta machine dedicated to polymer clay use — I use an Atlas 180 but you can improvise with an acrylic roller and playing cards if you’re pasta machineless.
Shape cutter of your choice (but squares are the VIPs in my opinion)
Polymer clay blade or craft knife

Step 1: Prep your clay

Give your clay a little warm-up stretch! No need to fully condition it just yet, mixing will take care of most of that. Just make sure it’s soft enough to cut without any fuss.

Step 2: Roll it out

Roll out all your clay to the same thickness. Whether you’re using a pasta machine or your favorite acrylic roller, consistency is the name of the game.

Step 3: Cut your pieces

Grab your cutter and cut out the parts for each recipe. Need fractions of parts? Slice and dice with your blade or knife until you’ve got just the right amount.

Step 4: Mix and mash

Combine your colors by squishing them by hand or running them through your pasta machine. Blend until you’ve got a smooth, even shade.

Step 5: Make magic

Now it’s time to create something amazing with your gorgeous new palette!

I’ve done my best to match these colors while staring at my screen, but keep in mind, colors may vary slightly depending on your screen settings (phone, tablet, laptop, etc.) The colors you mix should be super close, but don’t stress if there’s a tiny difference, it’s all part of the creative journey!

Your Turn to Play

Which hue is warming your creative hands first? The soft swirl of Buttercream Mist, the grounded calm of Hearthstone, or the golden glow of Maple Drizzle? Maybe Pumpkin Glaze has you dreaming of patchwork earrings, or Spiced Ember feels like the moody base your fall creations have been waiting for.
