Yellow: full chroma lives near white
Yellow is the one family that keeps its strength when it is light. Its chroma peaks up near value 8, close to white, and falls away fast as the value drops. That is why a dark yellow reads as olive or brown rather than a deep yellow: there is no such thing as a dark saturated yellow, the pigment cannot hold both at once.
The 5Y page below is the mirror image of the red one. The filled chips climb to the top and thin out toward the bottom. Full chroma yellow lives near the top of the value scale, and it leaves the moment you take it down.

How the painters spend it
Every use below is drawn from a methods.art record, not invented for the page.
Yellow ochre was Zorn’s lit mass color, built up with lead white to carry the light across the form, a muted earth yellow rather than a bright cadmium. See how it worked against the ochre and gray field on the Anders Zorn page.
Yellow ochre is Daniel Bilmes’s yellow primary, and it intermixes with permanent rose, phthalo green, and white to open a range of subtle cool notes in the skin. See it charted on the Bilmes palette.
Frank Reilly premixed a yellow red string from Cadmium Orange down the nine values, then cross mixed it with the red string for the average flesh tone, the flesh strings that gave his students control over skin. See the organised palette on the Frank Reilly page.
