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 effective title without transient badges, if available. Collision suffixes such as 2 and 3 remain part of the identity
• otherwise the right-most segment of the active pane cwd
• otherwise the tab ID

Effective titles and cwd segments share the same name namespace, so a title and cwd that both resolve to x receive the same color.

"Assign" persists these key-to-color assignments across sessions. It uses an offline-generated farthest-first sequence and does not reuse an RGB color until the 512-color sequence is exhausted.

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".
