Color Themes

Vizb themes change chart-series colors only. They do not change backgrounds, axes, or the separate light/dark appearance setting.

Set the initial palette when generating a report:

vizb results.csv --theme westeros -o report.html

Viewers can switch among built-in themes from the palette selector in the generated report. The selection is saved in the browser and reused across reports.

Built-in palettes

Every built-in contains ten unique colors. Hover a swatch to see its position and hex value.

`default`

`vintage`

`meadow`

`westeros`

`essos`

`wonderland`

`walden`

`chalk`

`infographic`

`macarons`

`roma`

`shine`

`purple-passion`

Custom palettes

Pass two or more comma-separated #rgb or #rrggbb colors to use a brand palette:

vizb results.csv --theme "#ff6b6b,#4ecdc4,#ffe66d" -o report.html

Custom palettes can contain any number of colors from two upward. Vizb cycles through them when there are more series keys than colors. Invalid palettes produce a warning and fall back to default.

Custom palettes appear as Custom palette in the generated report selector. Selecting a built-in theme replaces that custom viewer preference.
