The Hours · boundary treatments without colour fills Four takes on the same inline day grid (Option 2 scale). The field goes white — transit bars sit narrower to the right and carry the only real colour. Every hour boundary gets an eyebrow start time in the left gutter, and hovering any planet glyph shows that hour’s start – end writ large — two ways to read the hours. Night (sunset → next sunrise) carries a light grey wash; sunrise / sunset ride as icons on dashed lines; now is the charcoal line.
Treatment A
Ruled hairlines
Every hour boundary is a hairline — solid by day, dotted by night — with the changeover time centered on the line and the hour’s glyph in the gutter between. Saturn’s (ruler) lines draw slightly heavier. Boundaries read precisely; the field stays calm.
The Day · hours & transits
Sunrise → sunrise
Treatment B
Tick rail
Hour starts live only on a left rail — tick + glyph, monochrome except the ruler. The field itself is almost untouched: the most usable canvas for events, with 3-hour rules kept whisper-faint.

Sunrise → sunrise
Treatment C
Neutral zebra
Alternating stripes of one neutral tint replace the seven planet colours. Boundaries emerge where the stripe flips; glyphs alone carry identity; only the ruler keeps a coloured edge.

Sunrise → sunrise
Treatment D
Labeled boundaries
Each hour start is a ledger rule with glyph + start time on the line, at left — the most explicit about start / end with zero fill. Ruler hours print darker.
