The source is where a study starts.
It is not what the study concludes.
Why this page exists
Some of our studies begin with a historical color relationship. Others begin with something noticed on a street, in a room, or in a previous study that raised a question and left it unanswered.
Where a study begins matters, so we record it. But a starting point is not an authority, and it is not a finding. What we conclude, we conclude from our own arrangements — and we say so on the study itself, including when the answer is still not yet.
How we work with a source
What we do
- Take a relationship as a starting point
- Measure our own colors to a documented standard
- Build our own arrangements and hold our own constants
- Record what we changed and what we kept
- Name the source plainly
What we don't
- Reproduce a published collection's selection
- Reuse its numbering or its codes
- Copy its translations, names or scans
- Present a historical source as evidence for our own claims
- Imply endorsement by anyone
Study lineage
Each study records where it started.
Area establishes hierarchy. Attention doesn't always obey it.
Observed from — the historic color studies of Sanzo Wada.
Tested through — three arrangements holding everything constant except which color occupies which region, then the same arrangement at three sizes.
What we found — not yet. Open and collecting.
