Color and value: the working charts
There are many palettes, and most of them work. What they share is not a list of tubes. It is a balance of primaries and a synergy between them, and that balance is what lets a small set of colors open a wide range of harmonies. Get the balance and the range follows. Miss it, and no number of tubes buys it back.
You can watch that principle hold across very different kits. Every chart is below, in full, so the differences and the overlaps are here to read side by side, from the palette Daniel paints from to the Munsell scale under all of them.
01Start with the palette Daniel actually paints from. See the muted triad first, burnt sienna, ultramarine, and yellow ochre, then permanent rose and phthalo green added to push the cools, with the mixes each group reaches shown beside them.

The Bilmes palette, charted. It lives here.
02Those five keep working once white comes in, and the shadows come from only two of them. See burnt sienna and ultramarine run the whole shadow range, warmer with more sienna, cooler with more blue.

The Bilmes shadows, from two pigments. It lives here.
03Glazed over each other, those two reach almost a deep warm black. Not a black from a tube. A built one. Set Daniel’s five beside Zorn now, and watch the same logic run on four: white, ochre, vermilion, and a black that reads as blue beside the warm colors.

The Zorn palette, charted. It lives on the Anders Zorn page.
04Zorn reached his cools by placing black next to warmth. Reilly reached his by value first. See every color pre-mixed into a string of nine steps, matched to a neutral gray string of the same values, so the value is settled before the brush moves.

The Reilly palette, strung by value. It lives on the Frank Reilly page.
05Four, five, nine. See all three palettes stacked as one chart, and the shared move in every row: balance a short set of primaries, and a wide range of harmony follows. That balance is the thing to watch, not the tube count.

Three palettes, one principle. It lives here. Also on the Zorn page, and the Reilly page.
06What every one of those balanced sets is measured against is Munsell. See a color split into three things you can name on their own: hue, value, and chroma, so you can hold a value steady while you drop the chroma, or match a value across two different hues.

The Munsell system, the scale under the palette. It lives on the Munsell guide.
07Laid out in three dimensions, it is not a tidy sphere. See each hue reach its strongest chroma at a different value: yellow high near white, blue-purple only down in the dark, so the solid is lopsided, a tree with branches of different lengths.

08Flatten that tree to one value and the hues run in ten families. See the forty steps close into a ring, the five principal families spaced by the five intermediate ones.

The forty-hue circle. It lives on the Munsell guide.
09Stand one family up on its own and you get a page. See value climb one way and chroma the other, the right edge ragged because the strongest chips exist only in the middle values. A red can be intense at a middle value and simply cannot be at a very light or a very dark one.

A single hue page, the 5R chips. It lives on the Munsell guide.
10Which is why the useful way to dull a color is not black or white, since both move the value while they lower the strength. See each color stepped instead toward a neutral gray of its own value, so the color quiets while the value holds. Same move whether it came from Zorn’s four, Reilly’s strings, or Daniel’s five.

Mixing toward gray, not black or white. It lives on the Munsell guide.
