Sol
“sun”
balancedsunlitmeasured
A sundial drawn in fine lines, with a slow shadow crossing the hours.
If you like Solarized, you will feel at home here.
Thin sundial rings and hour marks in two corners, with a long shadow line. Held still, as it is while you read.
The plate
A sundial is drawn in thin lines from the top right corner: rings, hour marks and a long shadow cast by the gnomon. A smaller set of rings answers it from the bottom left. By day the lines are soft teal and bronze on warm cream, and by night the same drawing sits on a deep teal page, like one room at two hours. While Claude works the shadow crosses the hour marks very slowly, and it stops where it is when the answer is ready.
While Claude works
The spinner takes one of these words in place of “Working”. When the app names the step it is on, that name stays.
- Measuring
- Counting the hours
- Reading the shadow
- Keeping time
- Marking noon
- Turning slowly
After a turn of 20 seconds or more, Sol plays a soft chime under a second and a half long.
With /tessera music, a quiet loop of its own plays while Claude works and stops when the answer is ready. It is off until you ask for it.

Measured
Low contrast. Body text is held at 7:1 to 10:1. Here it measures 8.4:1 in light and 9.2:1 in dark. Calm accents.
| Reading | Light | Dark |
|---|---|---|
| Body text on the page | 8.4:1 | 9.2:1 |
| Muted text on the page | 4.8:1 | 5.9:1 |
| Page lightness | 94% | 30% |
| Glass | 68%, 20 pt blur | 68%, 20 pt blur |
Contrast is the WCAG ratio. Muted text is held at 4.5:1 or better. Lightness is OKLCH, where 0% is black and 100% is white.

/tessera still stops the motion. Sound has three levels: /tessera quiet is silence,
/tessera sound is a chime after long turns (the default), and /tessera music adds the room's own
quiet loop while Claude works. Your choices are kept across sessions.
Only Sol
Each plate also installs by its own name, and its commands use that name, such as /sol still or /sol music.
/plugin install sol --marketplace btahir/tessera Where it shows
Themes appear in the Claude Code desktop and mobile apps. The terminal keeps its own colors. The chime plays on macOS only.
