@pgcd@mastodon.online @lxo@snac.lx.oliva.nom.br Correction: I misspoke earlier! While you can set the tab name (the text label) and customize its color, you cannot actually change the color of the tab itself (what would be even better indeed). Apologies for the confusion!

By the way, xfce4-terminal can also automatically set unique background colors per tab (when configured). It’s a subtle but helpful feature for keeping track of tabs at a glance.
