What You Need to Make Dark Green Icing:
- Gel food coloring: When you search "how to make dark green icingย with food coloring" there are a lot of sites that give formulas requiring specific shades of gel food coloring, so today I'm giving you formulas using the Wilton Color Right System so that you only have to purchase one set (instead of 25 random, one-off colors). I'm going to show you how to make dark green icingย with wilton food coloring, as well as a dark green using the generic liquid food colors you find at the grocery store.
- Frosting/Icing: While I give you the formulas below using buttercream frosting, you can also use this recipe for royal icing, easy cookie icing, or sugar cookie glaze! The colors will vary a bit depending on the type of icing you use, so you'll just have to adjust the color accordingly.
How To Make Dark Green Icing - 5 Ways
Each formula shows how to make a different shade of dark green using food coloring gel, using 1 cup of buttercream frosting. Note that the liquid food coloring formula (at the end of the post) is based off ยฝ cup frosting. If you've ever wondered how to make dark green buttercream, here's 5 different shades!

Mixing Food Coloring
The easiest way to mix food coloring is to scoop the frosting into a bowl and mix with a spoon or rubber spatula until all icing is blended. It is easiest to hold the bowl in one hand and stir it with the other, rather than trying to mix while the bowl is on the counter. Be sure to scrape all the icing from the bottom of the bowl, to ensure no white icing is left.
It is easiest to use a solid bowl (like ceramic) rather than a lightweight plastic.
Frosting Tips & Tricks
- Rather than buy 25 bottles of food coloring, invest in a verstaile set of gel food coloring that you can mix & match! My favorite is the Wilton Color Right System.
- It is easiest to use a solid bowl (like ceramic) rather than a lightweight plastic bowl.
- Avoid lemon extract, as the acidity in this can discolor your frosting (causing it to turn darker or brown).

How do I make my icing darker?
There are two easy ways to make icing darker:
- Add more food coloring, of course! Just be careful not taste it as you go to ensure you are not adding so much food coloring that you begin to taste it. If you want your frosting just a tad bit darker, dip a toothpick into the food coloring (rather than dropping it in). This allows you to add a tiny amount and best control the color.
- Place colored frosting in an airtight container and store in fridge. Allowing the frosting to sit for 1-2 days will allow the colors to deepen. When ready to use, thaw and restir the frosting to smooth it out.
How do I make my icing lighter?
If you've made the frosting darker than you'd like, you can dilute the color.
If you are just trying to achieve a light green color overall, dip a toothpick into the food coloring (rather than dropping it in). This allows you to add a tiny amount and best control the color. For lighter green frosting colors, check out my Christmas Cookie Frosting formulas.

Can I halve the drops to make a half-cup of frosting and still maintain the beautiful color shown in the 1 cup version?

That will work just fine as long as you can manage to get half drops!

I am so GLAD someone shared your information. Do you have a instructional book for mixing colors?

Hi Dawn! So glad you're here! I don't have an instructional book but I find that the color chart in the Wilton set is a great start. There's also some great charts online if you search "frosting color charts". Hope that helps!
