“A simple watercolor palette for beginners (and experts)”. Spelled out as Winsor & Newton brand colors, plus their universal pigment names: ☛ cyan: Winsor Blue (green shade) PB15:3 a.k.a. Phthalocyanine Blue; ☛ magenta: Quinacridone Magenta PR122; ☛ yellow: Winsor Yellow PY154 a.k.a. Azo Yellow Light a.k.a. Benzimidazolone Yellow; ☛ black: Payne’s Gray PB15+PBk6+PV19.  Extra colors for extreme cases - forming a kind of a modified “split primary” palette in the end: ☛ black: “Lunar Black” from Daniel Smith PBk11; ☛ green: Winsor Green (yellow shade) PG36; ☛ violet/purple: Winsor Blue (red shade) PB15:1; ☛ red: Cadmium Red Medium PR108.  Note: those are mostly staining colors, which reportedly has a number of advantages, but also results in less “typical watercolors texture”.  Some deeper exploration with some scientific background as well at: “Watercolor Palette Building III: Choosing a CMY Primary Triad” and the connected playlist.
