ChartBar paints its output in named regions. Each region is a ChartBarStyles value you can recolor per control instance.

ℹ️ Styling is per control — there is no global “style all charts” API. The only style-related global setting is PromptPlus.Config.ContrastRatio.

The ChartBarStyles regions

Region	What it paints
Prompt	The prompt text
Error	The validation error line
Selected	The highlighted / current chart item
ChartLabel	The item labels
ChartValue	The numeric values
ChartPercent	The percentage values
ChartTitle	The chart title (Title)
Answer	The confirmed answer shown after .Run()
Pagination	The page indicator

Recoloring a region

Use the fluent Styles method. A Style is a foreground color, a background color, and an Overflow strategy — there is no bold/italic/underline. A bare Color is accepted as shorthand for a foreground-only style.

using ConsolePlusLibrary;
using PromptPlusLibrary;

PromptPlus.Controls
    .ChartBar("Select item")
    .AddItem("North", 120).AddItem("South", 80).AddItem("East", 95)
    .Title("Sales by Region")
    .Styles(ChartBarStyles.ChartTitle,   Color.Yellow)
    .Styles(ChartBarStyles.ChartPercent, Color.Cyan)
    .Styles(ChartBarStyles.Selected,     new Style(Color.Blue, Color.Default))
    .Run();

To reuse a theme across charts, wrap the styling in a helper you call for each control — the library does not broadcast styles for you. See Global Styles for the pattern.

Bar colors themselves come from AddItem’s colorBar argument (or the automatic rotating sequence), not from ChartBarStyles. Use Styles for the labels, values, percentages, title, and other text regions.

Contrast enforcement

PromptPlus nudges foreground colors that fall below the configured contrast ratio so text stays readable on any terminal theme. Tune or disable with PromptPlus.Config.ContrastRatio.
