tab_bar_color_mode = "Off"#

Controls built-in per-tab background coloring in the tab bar.

Possible values are:

• "Off": disable built-in tab color assignment
• "Hash": deterministically hash each tab identity to a generated color
• "Assign": persist first-seen tab identities and assign new colors to stay distinct from prior assignments

When assigning colors, wakterm keys each tab by:

• the explicit tab title, if set
• otherwise the right-most segment of the active pane cwd
• otherwise the effective title

"Assign" persists these key-to-color assignments across sessions.

Generated colors are only applied when your format-tab-title callback has not already set explicit foreground/background colors for the tab.

Use tab_bar_color_intensity to adjust how much generated tab backgrounds are dimmed in the active, hover, and inactive states.

The default is "Off".
