Unlocking the Power of a Limited Watercolor Palette: How 3 Colors Can Paint a Garden

I’ll admit it… I’m a color junkie. I absolutely love bold, vibrant color—and I have the overflowing paint drawers to prove it. Every time a juicy new tube of watercolor hits the art store shelf, I feel the magnetic pull to add it to my collection.

But here’s the thing I’ve learned as a watercolor instructor: Beginners don’t need a rainbow to create beauty. In fact, giving a student a huge list of paints to buy can feel overwhelming and discouraging, especially if they’re just starting out and don’t yet know how to use them. That’s why I’ve become a big advocate for teaching with a limited watercolor palette.

I just wrapped up teaching a 4-week online watercolor and drawing class focused on spring bulbs through the Coastal Maine Botanical Gardens. (I am teaching a 5 day workshop there in the fall!) It was such a joy! My students came in with different skill levels, and each brought their own unique style and perspective. I always encourage creative exploration and experimentation—but I also understand how intimidating color can be for some.

Mixing colors, choosing the “right” pigment, and layering watercolor washes can feel overwhelming—especially when you’re also trying to learn how to draw flowers like tulips, or daffodils. That’s why, for our final class, I introduced a limited primary color palette using just three professional watercolor paints.

Why Use a 3-Color Watercolor Palette?

Limiting your palette doesn’t limit your creativity—in fact, it unlocks it. I chose just three primary watercolor pigments:

• Quinacridone Magenta (QOR Watercolors)

• Ultramarine Blue (Daniel Smith)

• Hansa Yellow Light (Daniel Smith)

Using these as my primary colors, I created a full color wheel to demonstrate how many beautiful hues you can achieve with just three paints. By mixing the two adjacent colors, I was able to produce vibrant secondary colors like orange, purple, and green. These mixtures—often referred to as analogous—create harmonious transitions that are ideal for painting natural subjects like flowers.

Beneath the wheel, I created smaller blocks to show how mixing all three colors in varying proportions can create subtle neutrals and deep shadows. By adjusting the water levels and layering washes, I was able to expand the range even further—perfect for capturing the folds and shadows in botanical watercolor art.

Putting It into Practice: Painting the Parrot Tulip

After completing the color mixing exercise, I used my new palette to paint a vibrant parrot tulip. With just these three watercolor paints and some planning, I achieved a wide range of rich, glowing color—without reaching for a single extra tube.

Whether you’re just starting your watercolor journey or you’re a seasoned artist looking to simplify your palette, I encourage you to try this exercise. It’s a great way to build confidence in color mixing, and it’s especially helpful for painting spring flowers, botanical subjects, and anything inspired by the natural world.
