useWhen: the palette comes from the user's wallpaper

Material You arrived with Android 12 in 2021 as the personalization half of Material 3.
The system picks source colors out of the wallpaper, expands each into a tonal palette
of thirteen fixed lightness steps, and hands apps a set of roles filled from those
steps. An app that asks for the primary role rather than for a specific blue gets the
user's blue, and every app that does the same shifts together when the wallpaper
changes. The extraction engine was called Monet inside Google, and the name stuck in
the modding community long after the docs settled on "dynamic color".

The machinery underneath is a color space, HCT, that pairs the hue and chroma of
CIELAB with a tone axis borrowed from a contrast model, so tone 40 against tone 100 is
a guaranteed contrast ratio no matter which hue the wallpaper produced. That is the
whole trick: because lightness is standardized and hue is not, an unpredictable seed
can drive a predictable, accessible scheme. It also means the design has to be written
against roles such as primary, surface, and on-surface rather than against literal
values, which is the same discipline a design system asks for with its color tokens.

Two things follow for anyone building on top of it. First, brand color and dynamic
color are in tension, and you have to decide which one wins per surface: a payment
confirmation may want the brand, a home screen widget almost never does. Second,
nothing in the scheme is a constant you may hard code, so illustrations, charts, and
anything with a fixed palette need their own answer before the wallpaper picks one for
them. The look also travels beyond Android, since the same tonal palette approach shows
up wherever a product wants a theme it can generate rather than draw by hand.

The phrase is also used loosely, and it is worth keeping the parts separate. Material 3
is the design system, dynamic color is the mechanism, and Material You is the
personalization it makes possible: the large round shapes, the wide corner radii, and
the pastel surfaces of the 2021 refresh are Material 3's own visual language, and they
persist whether or not a device is theming from anyone's wallpaper.
