Your first month is free, enough to take this course at no cost. ## What it actually covers Aima Kessy's class opens with a real argument, not just a materials list: traditional color theory, built on an 18th-century red-yellow-blue color wheel, misrepresents how pigments actually behave when mixed. The middle third of the course backs this up with specifics. It explains why cyan, magenta, and yellow produce broader, more saturated mixing ranges than red, yellow, and blue, walks through why red and blue pigments can't mix a truly bright violet (they lack a shared reflectance in the violet wavelengths), and traces the split-primary palette back to a flawed 18th-century assumption about pigment "impurity." This isn't watered-down science communication. It's a genuine attempt to update the mental model most watercolor students are handed by default. From there the course pivots to application. Using the Munsell color system (hue, chroma, value) and brand-specific colormetric charts like Schmincke's, Kessy demonstrates a concrete process: locate a target color on the chart, find pigment pairs or triads whose mixing lines pass near or around it, then physically test the combinations while tracking tinting strength, transparency, and drying shift. The mixing-darks lesson is the sharpest practical payoff, showing how PG7 and PR122 look like visual complements but actually mix a muddy violet, while PG36 paired with the same magenta produces a much cleaner near-black. That distinction, tested pigment-to-pigment rather than assumed from a wheel, is the class's most transferable skill. ## The project and its limits The color recipe book project ties theory to a physical, ongoing reference object rather than a one-off exercise, and the accompanying journal setup (a separate space for messy experimentation versus curated recipes) is a genuinely useful workflow habit independent of the color theory content. The tints/tones/shades exercise and the color-matching drills (paint chips, leaves, photographs) round out the practice with low-stakes repetition designed to build intuition rather than memorized formulas. Where the course falls short is depth of guided painting. Most of the runtime is swatch-based experimentation rather than applied composition, and the "Playful Experiments" lesson mostly gestures at painting practice rather than walking through one. At 81 minutes across sixteen lessons, some sections move quickly, particularly the science explanation of cone cells and wavelength absorption, which is accurate but compressed enough that a viewer with zero background in color science may need to rewatch it. This is not a class for someone who has never held a watercolor brush. Kessy says as much upfront, pointing newcomers toward a separate essentials class first. It rewards someone who already has basic paint-handling comfort and has hit the specific wall of getting muddy or unpredictable mixtures despite "knowing" the color wheel. For that viewer, the reframing from abstract color relationships to pigment-specific mixing behavior is worth the time, and the recipe book gives the ideas a lasting home rather than letting them evaporate after the last lesson. The standout The lesson on finding mixing complements by testing specific pigment pairs (not fixed color-wheel opposites) directly fixes the common problem of muddy, unpredictable dark mixtures. ## What you will learn - · How to distinguish visual complementaries from mixing complementaries and use both intentionally - · How to read a colormetric position chart (Schmincke) or artist color wheel to plan pigment pairs before mixing - · A repeatable process for hue-matching a target color using two-paint or three-paint (triad) mixing strategies - · How to mix custom darks, neutrals, grays, and earth tones without relying on tube blacks - · How to build a personal color recipe book and mixing journal to document reusable pigment combinations - · How to color-match paint chips, natural objects, and photographs to sharpen intuitive mixing judgment Best for: Watercolorists who already know the basics of paint handling and want a more analytical, pigment-specific approach to mixing rather than another beginner color-wheel primer. Skip it if: Absolute beginners with no watercolor experience at all, since the teacher explicitly recommends a foundational tools-and-techniques class first.
