Primary Watercolor Paint Sets are available in two distinct palettes, each designed to support different styles of watercolor work in classrooms, homeschool studios, and mixed‑age learning environments.
Both sets use Stone’s handcrafted, highly‑pigmented watercolors and come in 1 oz, 4 oz, or 8 oz sizes.
1. Classic Primary Set
True Red • Lemon Yellow • Ultramarine Blue
The Classic Primary Set is the foundational trio used in early watercolor lessons. These three colors support the traditional Red–Yellow–Blue approach taught in Grades 1–3, where children explore luminous washes, gentle blending, and the creation of clear secondary colors.
- True Red — A ready‑to‑use primary red made with a quinacridone pigment for clarity and clean mixing—no blending required.
- Lemon Yellow — A cool, transparent yellow that creates bright greens and crisp oranges.
- Ultramarine Blue — A warm, atmospheric blue ideal for veil painting and early‑grade color stories.
This set is perfect for teachers following the classic Waldorf curriculum, veil painting, and any lesson where calm color transitions and gentle brushwork are the focus.
2. Bright Primary Set
Red Rose (Magenta) • Lemon Yellow • Phthalo Blue
The Bright Primary Set offers a vivid, cool‑leaning palette for cheerful, high‑chroma color exploration. Rose (magenta) and Phthalo Blue create brilliant purples and greens, while Lemon Yellow provides clean, bright mixes across the spectrum.
- Rose (Magenta) — A cool, luminous red that produces clear purples and vibrant secondaries.
- Lemon Yellow — The same cool yellow used in the Classic Set.
- Phthalo Blue — A cool, high‑chroma blue that mixes bright greens and bold purples.
This trio is ideal for homeschool families, mixed‑age classrooms, and artists who prefer a lively, vivid palette.
Why Two Primary Sets?
The Classic Primary Set supports traditional color mixing and veil painting, while the Bright Primary Set offers a vivid alternative for color‑theory lessons, mixed‑age groups, and families who want cleaner, brighter secondaries.
