Overview
Duration estimates show as small tags on your tasks, like 15m or 1h. You can choose what color those tags are, for example matching each task's category so you can see where your time is going at a glance.

Choosing the color (web and desktop)
Open ☰, click Features (or press S), find Duration Estimates and open its settings. Under Duration tag color, choose:
Theme: your theme's main color (default).
Gray: a quiet gray.
Category: the color of the task's parent category.
Custom: pick any color with Custom color.
You can also change this from the Style sidebar (☰, then Style), in the Tag Style section, under Duration Color. It's the same setting.
Choosing the color (mobile app)
In the mobile app, open Features from the menu and open the settings for Duration Estimates. Under Duration tag color, choose Theme, Gray or Category. Under Header duration totals, choose Show or Hide for the totals above your lists. The mobile colors are set separately from the web and desktop ones.
