Start with context.
The Japan entry brings together Katsura Imperial Villa, washi paper, wood and regional craft. Follow its sources before borrowing its visual language.
Read the Japan entryChromologium is an independent design archive and working laboratory for colour, material and interaction. Explore a source, try a behaviour, and take a system into your own project.
A sheet of paper gives light an edge. Lacquer changes with the viewing angle. A spring makes weight perceptible through movement. These details give the archive something specific to study.
Chromologium brings writing, visual design and software engineering to that question. Its systems explore how colour, spacing, type and motion can work together, and let you compare the decisions on screen.
The aim is to give designers and developers a shared place to notice, experiment and choose.

The archive is designed to move from attention to action. Each path gives you a different kind of evidence to take into the next thing you make.
Trace a place, practice or object with provenance attached, so the visual decision has somewhere specific to begin.
Open the Atlas A TESTED BEHAVIOURRun a principle through light, colour, type or motion and see what changes before you commit it to a screen.
Enter the Laboratory A PORTABLE DECISIONKeep the rationale with the result: compare a formulation, export its tokens, or hand the study to someone else.
Visit the packing deskJapan's Atlas entry connects to Kyoto Urushi. Here is how to read that relationship: historical references first, then a contemporary palette and interaction study.
The Japan entry brings together Katsura Imperial Villa, washi paper, wood and regional craft. Follow its sources before borrowing its visual language.
Read the Japan entryKyoto Urushi pairs indigo grounds with pale text and gold accents. These are authored interface colours, rather than pigment measurements or a reconstruction of a historical object.

CURRENT FORMULATION / lightHistorical objects and buildings have their own contexts. Image credits identify the media source; the palettes and interface behaviours are contemporary interpretations.
Each note keeps the reference, the interpretation and the usable result in the same frame. Follow one to see the decision under its own conditions.
Start with a place, pigment or craft. Open an Atlas entry to find the references, palette and related interface studies.
Explore the Atlas 02Adjust a spring, redirect light or compare a colour pair. The Laboratory makes a design decision something you can try.
Try an instrument 03Compare systems in light and dark, inspect their components, then export the active palette into a project of your own.
Find a systemFor the ideas behind the experiments, read the curatorial monographs or follow a term through the Lexicon.
A useful study shows where it came from, what it calculates and what still needs judgement.
Chromologium is curated and built by Evelyna Bellamy, Curator & Principal Systems Architect at Temporal Architecture. Writing, interface design and software engineering meet here through studies of colour, material and interaction.
The full author record below sets out that interdisciplinary context: the education, continuing study and wider work informing the archive, with links to the supporting records.

Curator & Principal Systems Architect
Temporal Architecture · Folio MMXXVI
Evelyna Bellamy investigates the architecture of material memory, engineering zero-dependency computational substrates, diurnal solar synchronization, and diegetic design systems that resist digital ephemerality. Her work bridges formal software engineering with empirical research into predictive systems, cognitive interaction ergonomics, and human-centered communication.
