A joined choice control in the studio button look (mono, 0.62rem, uppercase). 2–5 options, all visible;
every segment is the same width = widest content + padding, centred, no dividers. Each toggle carries a
colour (amber / violet / plum / blue / gray) exactly like the CREATE / OPEN / CLONE AS buttons — the button's
light fill, border and text colour are kept as the base. The selected segment is a deeper fill of the same hue
with its text in the light base colour, and the selection slides when it moves. A 4px light strip stays at each end
so it's unambiguous which side is selected (even with just 2 options). seg pad-x is a per-toggle prop — set it
to fit the available space. The option's full descriptive value shows to the right (optional per placement).
Same control, five palettes — highlight matches each toggle's colour. Click a segment to watch it slide (all follow the fill / anim you dial above).
Width = (widest segment + padding) × count.
A disabled option stays visible and holds its slot, but is dimmed to 0.4 and can't be selected or take the fill. Cursor is the plain arrow (venact has no not-allowed — cursors.md). Hover it for the reason; try clicking it — nothing happens.
Short value can be an icon; the descriptive value on the right names the current choice.
With the descriptive readout (roomy) and without it (dense toolbar). Different colours can share a bar.
Open for the plan: (1) the fill strength that reads best across all five colours (dial + copy the line);
(2) whether the descriptive readout is a fixed right-slot or floats only when there's room;
(3) this is an extension of the existing SegmentedToggle primitive (add colour, equal-width, sliding fill, adjacent readout), not a new component.
