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.
A palette is also a baseline, not a rulebook. Cohesion, balance, and range make it work, and more colors do not make it better. They make it more complex, because the harmony gets harder to hold. So the core stays small, and when a subject demands a note the core cannot reach, a bright sky, a luminous sunset, you bring a color in for that painting and set it down after. The charts here are guidelines and explanations of how it works, not the best palette, because that varies too.
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, the palette itself, each color with its job. See the muted triad first, burnt sienna, ultramarine, and yellow ochre, then permanent rose and phthalo green added to push the cools, and the two whites that sit beside them as members of the palette, one transparent, one opaque.

The Bilmes palette, charted. It lives here.
02Two whites, because white is not one thing. See lead white behave as a transparent light, the color beneath plus the glaze making a third color, four or five subtle layers building a luminosity one layer cannot, while titanium covers the same warm ground in one opaque pass. And lead is actual lead, never handled casually.

On whites, the two whites compared. It lives here.
03Those 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.
04Glazed 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.
05Zorn 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.
06The limited palettes above descend from older, fuller kits, and two of them mark the poles. Start with the darkest: see sienna and umber laid toward a bituminous near-black, the tonal manner the Munich Academy taught, its form pulled from shadow by one covered window rather than by bright paint.

The dark Munich palette. It lives here.
07Then the opposite pole, an older palette that holds nothing back. See the ten pigments of Pacheco’s Seville workshop, two earths, two blues, a copper green and the rest, the full kit a young Velazquez ground by hand and trained on. The modern kits strip that abundance back down to four, five, and nine.

The Seville workshop palette. It lives here.
08Hold the premise every kit sits on: a palette is a baseline. See Daniel’s constant row carry most of portraiture, and the deliberate bring-ins wait at the edge, each with its trigger, a Prussian blue for painting outside, a perylene red occasionally, the cadmiums when a note must be luminous, cobalt or cerulean for a bright sky ultramarine cannot make.

The palette is a baseline. It lives here.
09That baseline holds for a small kit. A whole teaching line bets the other way, on many high-chroma colors, and it still runs today. See it move from Henry Hensche’s bright cadmium palette, the one his student recalled since Hensche kept no list of his own, to Nelson Shanks’s larger one, then the same notes respelled in current single-pigment tubes, a French Vermilion coded PR255 with PY170 where a toxic cadmium scarlet once sat. The honest part sits underneath: newer is not always more permanent, so the cadmiums keep their place.

Contemporary palettes, the living line. It lives here.
10Four, 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.
11What 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.
12Laid 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.

The Munsell color tree. It lives on the Munsell guide.
13Flatten 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.
14Stand 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 reds page.
15Now stand each of the other families up the same way. See yellow break the pattern first: its filled chips climb to the top, strongest up near white at value 8, and thin out into olive as they darken. The opposite of red.

The 5Y page, yellow near white. It lives on the yellows page.
16See green reach only modestly. Its edge bulges in the middle, around value 5, and stops well short of where red ran out to, which is why a saturated green is a quieter thing and a limited palette can skip the green tube.

The 5G page, green in the middle. It lives on the greens page.
17See blue fall shortest of the four. The grid barely leaves the neutral column, strongest low near value 4, the humble family that never gets far from gray. Ultramarine sits lower still, down in the dark.

The 5B page, the humble blue. It lives on the blues page.
18Which 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.
How color behaves in the eye
The charts so far name and measure color. These last four show how it behaves once it is on the canvas: a value shifts against the values around it, a color shifts with its neighbor, separate dots fuse into one, and the three ways painters have mapped all of it do not agree.
19Start with value, because a value is never absolute. See the same gray read lighter on a dark ground and darker on a light one, and a light object in shadow come out lower in value than a dark object in the light. The three brackets group by that relationship, not by a fixed number.

Tonal relationships, value is relative. It lives here.
20A color is never alone either. See the same neutral gray change on a red, a green, and a blue ground, borrowing the opposite of each, and two complements share an edge that will not sit still, the effect Delacroix worked on purpose to make his color carry.

Simultaneous contrast, Chevreul’s law of 1839. It lives here.
21Now let the eye do the mixing. See blue and yellow laid as separate dots fuse, from a step back, into a lighter green than the same two make mixed as paint, the method Seurat built his whole canvas from.

Optical mixing, Rood’s Modern Chromatics of 1879. It lives here.
22So which map do you trust? See the even RYB wheel, Ostwald’s tidy solid, and Munsell’s lopsided tree together, and why the one the forty-hue circle and the tree above are drawn from is the one the eye actually keeps.

Three ways to map color. It lives here.
Three of the palette charts above run through a lesson, with a mixing exercise from the Finishing Touches demo.
