swatch.library.save replied with the number of solid colors and
gradients it was asked to save, including the gradients the format
leaves out. For a new document saved as .ase, count was 50 and the file
held 46 colors. The .gpl and .ase writers keep solid colors only, and
the CSS writer leaves freeform gradients out.
count is now the number of swatches written. The new
PaletteFormat::holds returns whether a file of a format keeps a swatch
with a given paint, and swatch.library.save counts the swatches for
which it returns true. The reply has the same fields as before.
Tests: after a freeform gradient is added to a new document's swatches,
the test checks that count has these values: 51 for .vcswatches, 46 for
.gpl and .ase, and 50 for CSS. Each file holds that many swatches.
Docs: docs/mcp.md.
swatch.library.copyToUser {library} copies a library loaded from
another folder into the user library folder of the desktop app. A
.vcswatches, .gpl or .ase file is copied as it is; the swatches of a
document and a library loaded from the data or dataBase64 parameter are
written as a .vcswatches file. The copy gets a name that no file in the
folder has, and when a file with the same extension and bytes is
already there, that file is used. The library is then listed as User
Defined only. Until the app quits, commands given its loaded id use the
copy, unless another library is loaded under that id. Without a user
library folder (the web and headless sessions) the command is disabled.
A file with the same extension and bytes as a User Defined library
opens as that User Defined library. The unchanged original of a copied
.ase file is one such file. Graphic style libraries open the same way.
The Save Swatch Library dialog lists Swatch Exchange (.ase) as a
format, and swatch.library.save takes format: "ase" or a path ending
in .ase. Each solid color keeps its model (RGB, CMYK, Lab or Gray) and
its type (spot, global or process), and color groups stay groups.
Gradients and patterns are left out, and a tint swatch is written as
the color it shows. Without a path or user: true, the command returns
the file as dataBase64.
A swatch exchange library opens under the name of its file. When Save
Swatch Library or Save Graphic Style Library saves to a file, the save
panel suggests the Name from the dialog as the file name, as a save to
User Defined does, and the web app downloads the file under that name.
A name made only of dots and spaces, such as "...", gives the file name
Library (Library.vcswatches) in place of a hidden file.
palette_io::write returns the file's bytes. A property test writes
generated libraries and reads them back, and an import fuzz test loads
mutated copies of a file the writer wrote.
File › Open, Other Library… and the User Defined library folder read
.ase files. Colors keep their model, global and spot colors stay global
and spot, and color groups stay groups. The library readers take a
file's bytes. On the web, File › Open passes a swatch library file to
swatch.library.load as dataBase64 instead of as lossy UTF-8 text.
Swatch and group names in a library are now unique, in .gpl files too.
Add to Swatches puts each color group of a library into one document
group when the document already has a swatch with the group's name.
The library fuzz helpers fail when a command panics.
A colour linked to a global or spot swatch keeps a tint (Paint::Solid.tint, 1 by default and
left out of files at 100 %): paint.setFill/setStroke {swatch, tint} apply the swatch at that
percentage, swatch edits recolour every linked colour at its own tint, and Color::tinted
resolves it (CMYK and Gray inks scale, RGB mixes toward white). swatch.new saves a tint as a
tint swatch ("Ink 40%") linked to its base. Spot tints separate as that percentage of their
plate (Separations Preview, PDF Separation value) instead of an ink-ratio guess. Adjust Color
Balance's Global mode (tint) shifts the tints of linked colours. The Color panel shows Tint
mode (the swatch chip, its name and a T slider) for linked colours; the Swatches panel
highlights the tint swatch in use. Gradient stops get the same link and tint fields (the
swatch walks cover them), so GradientStop is no longer Copy.

Window > Swatch Libraries > Gradients lists five generated gradient
libraries (Spectrum, Sky, Neutral incl. fades to transparent, Duotone,
Radial Glows); the library panel's menu lists them too.
Swatch Options on a gradient swatch shows its name and the gradient; OK
renames it. Alt-dropping an edited gradient (or a colour) on a swatch of its
kind in the Swatches panel replaces it, via swatch.edit {paint}.

Save Swatch Library… (Swatches panel menu, libraries menu, Window menu)
opens a dialog: name, format and destination. .vcswatches is lossless JSON
(colour models, global, spot, gradients, groups), .gpl an RGB palette with
groups as comment headers, CSS custom properties with escaped names.
Libraries saved to the user library folder show under User Defined.
Other Library… (and opening a .vcswatches/.gpl file) loads a library or
another document's swatches into the library panel.
Commands: swatch.library.save {path?, format?, names?, name?, user?}
(no path returns {data}), swatch.library.load {path?|data?|dataBase64?,
name?}; UI: window.swatchLibrary.other, ui.saveSwatchLibrary (dialog
saveSwatchLibrary), window.userSwatchLibrary1..10.

Window > Swatch Libraries and the Swatches panel's library button open a
read-only, floating library panel (thumbnail and list views, find field,
libraries menu, previous/next arrows). Clicking a swatch adds it to the
document and applies it as one undo step; Shift/Cmd-clicks select swatches
and groups for Add to Swatches. Default Swatches restores missing defaults.
Libraries are computed in code (OKLCH, rounded to 8-bit sRGB): Web Safe 216,
Grays and Neutrals, Earth Tones, Skin Tone Ramps, Pastels, Brights,
Metallic Gradients, Perceptual Scales, Harmony Sets.
Commands: swatch.library.list, swatch.library.get, swatch.library.add
{library, names?, apply?, focus?}, swatch.resetDefaults {replace?};
UI command window.swatchLibrary {library}.
