Use it

1. Open your artwork in CSP.
2. File > Connect to smartphone (Datei > Mit Smartphone verbinden) — a toggle, so picking it again turns Companion Mode off. Leave the QR open.
3. Select Connect. The dot turns green.
4. Pick a source and your counts (6 major, 6 minor).
5. Extract palette. The .aco lands under %LOCALAPPDATA%\CSP Palette Companion.
6. Drag the green Drop onto CSP Color Set bar, not a swatch, onto CSP's Color Set palette.

Before picking an Auto Action: CSP exposes the command name only, never its recorded steps. The app runs whatever you point it at, unchecked. Record one, test it on scrap.

How the palette is made

Your picture gets shrunk; see-through, near-black and near-white pixels thrown out — nobody paints with those. The rest go into buckets of look-alike pixels; each bucket's average is one swatch. Biggest buckets: major. Oddballs: minor.

1600x1000, 220 ms, six and six.

Major #1A2535 deep sky · #48334D purple ridge · #3D4B65 sky over ridge · #804C58 dusk · #B26367 water · #F4B66E sun

Minor #EC6CA8 pink dots · #77DAE6 cyan dot · #276060 green hill · #674153 ridge edge · #252346 night sky · #4A3F68 ridge shadow

Those dots are under one percent of the picture — and the two colors an artist wants. Small and distinct beats large and dull. Same palette every run. Technical version.
