Fall Cookie Color Palette: AmeriColor Royal Icing Color Formulas

One of my favorite parts of decorating fall cookies is creating a color palette that captures all those warm, earthy shades of the season. For these fall leaf cookies, I wanted a palette that felt rich and autumnal without being overly bright, so I mixed five custom shades using AmeriColor gel food coloring. Below, I’m sharing the exact color combinations I used to create each shade, along with photos of the finished icing and cookies so you can easily recreate this fall color palette for your own cookie decorating projects.

Tips for Mixing Fall Icing Colors

Before diving into the individual color formulas, here are a few tips that will help you create rich, coordinated icing colors while avoiding some common coloring problems.

Start with Less Color Than You Think You Need

When adding gel food coloring to royal icing, start with a small amount and gradually add more until you get close to the shade you want. Gel colors are concentrated, and it’s much easier to darken icing than it is to lighten a color that has gone too far.

It’s also important to remember that royal icing colors will deepen as they sit and can become even darker as the icing dries on the cookie. I usually stop mixing when my icing is about two shades lighter than the final color I want and allow time for the color to develop. For example, when making black royal icing, the freshly mixed icing can look more like a dark charcoal gray. As it rests and dries, it will continue to deepen into black.

Create a Cohesive Color Palette

Even when individual icing colors look beautiful on their own, they don't always look like they belong together. One trick I like to use is to mix a tiny amount of each color into the other colors in the palette.

For example, if your palette includes orange, yellow, green, burgundy, and brown, add just a touch of your orange icing to each of the other colors. Then add a tiny amount of yellow to the remaining colors, and continue the process with each shade in your palette.

You only need a very small amount, you don't want to noticeably change the individual colors. The goal is to introduce a subtle hint of the same underlying tones throughout the entire palette.

This helps harmonize the colors, softening any shades that might otherwise feel too bright or disconnected and giving the entire palette a more unified look. It's especially helpful for fall palettes, where slightly muted, earthy colors tend to look more natural together.

Once your colors are mixed and harmonized, you're ready to move on to the individual shades and formulas I used for this fall cookie palette.

Fall Royal Icing Color Palette

Now for the colors! This fall palette includes five warm, earthy shades inspired by autumn leaves. Below, I’m sharing the AmeriColor gel combinations I used to create each color, along with photos showing how the finished shades look in royal icing and on decorated cookies.

Keep in mind that these formulas are best used as a starting point rather than an exact recipe. The final shade can vary depending on the amount of icing you're coloring, how much gel is added, and how long the icing has had to develop. For larger or smaller batches, simply keep the same general color ratios and adjust as needed.

Burnt Orange Royal Icing

Burnt Orange is a warm, muted orange royal icing color that captures the look of changing fall leaves. This earthy orange works especially well for autumn leaf cookies, pumpkins, and other fall cookie designs. I created this shade by combining AmeriColor Orange and Americolor Chocolate Brown.

Gold Mustard Royal Icing

Gold Mustard is a warm, golden yellow with a slightly muted tone that keeps it from looking too bright. It's a beautiful shade for fall leaf cookies and adds a lighter pop of color alongside deeper oranges, reds, greens, and browns. I created this shade by combining AmeriColor Egg Yellow and Americolor Chocolate Brown.

Mossy Green Royal Icing

Mossy Green royal icing is a soft, earthy green inspired by the muted greens found in autumn foliage. Its natural tone helps balance the warmer colors in the palette and works beautifully for fall leaves, greenery, and woodland-inspired cookies. I mixed this shade by combining Americolor Leaf Green, AmeriColor Lemon Yellow and Americolor Chocolate Brown.

Deep Burgundy Royal Icing

Deep burgundy royal icing is a rich, deep red inspired by the dramatic colors of maple leaves in the fall. This darker shade adds depth and contrast to a fall cookie color palette without feeling as bright as a traditional red. This shade was made by combining Americolor Super Red, AmeriColor Regal Purple and Americolor Super Black.

Chestnut Brown Royal Icing

Chestnut Brown royal icing is a warm, earthy brown that grounds the entire fall color palette. It's a versatile neutral for autumn cookies and works especially well for fall leaves, acorns, tree details, and other nature-inspired designs. I created this shade by combining Americolor Chocolate Brown and Americolor Super Black.

A Fall Palette Ready for Decorating

And here’s the finished palette in action! Seeing all five colors together on these fall leaf cookies really shows how well the warm, earthy shades complement one another. From the golden yellows and rich oranges to the deeper reds, greens, and browns, the finished cookies have plenty of contrast while still feeling like one cohesive autumn palette.

I hope these AmeriColor formulas give you a helpful starting point for your own fall cookie decorating projects. Feel free to adjust the shades to make them lighter, darker, or more muted to suit your designs. And don’t forget to save this palette to reference the next time you’re mixing colors for fall cookies!
