Cannot display colors with watch

# Description

dysk never outputs color with watch -c.

I'd expect this usage to be possible with `--color yes` (or force?).

# steps to reproduce

- use `watch -c dysk --color yes`

**expected** the output is colored

**actual** output is not colored.

# additional info

Some tools behaves this way. Ex the crate `dua` does output colors when executing `watch -c dua`.

Start by reproducing the issue with `watch -c dysk --color yes` and trace the CLI's color-handling entry point. Done means dysk emits colored output in that invocation, matching the expected behavior described in the report.
