Read the appearance distinction
Google documents Dark mode as an appearance choice for areas such as the homepage, toolbar and settings, and notes that Incognito can also look dark. The colour of a window is therefore not enough to identify its browsing-session type. Use the actual browser indicator and context rather than the background colour alone.
Consider a shared-computer assumption
Someone might open a dark-themed ordinary window and assume it has private-session retention rules. Another person might see a dark player page and make the same inference even when the browser itself is using a light theme. These are illustrative appearance confusions, not observations of a particular user’s device.
Check before entering account details
Identify the actual browser window and profile, and read the intended website address. Decide whether the computer and account context are appropriate for the task. A theme does not create a new user account, remove an existing website login or establish that downloaded files will be handled privately.
Keep the support description concrete
When comparing a player in regular and private contexts, name those contexts explicitly and retain the browser version. Do not report that the black window works while the white one fails and expect that to describe privacy state accurately. Appearance is useful for orientation, but the actual session and selected settings are the evidence needed for diagnosis.
Questions, answered
Can ordinary Chrome use a dark appearance?
Yes. Google documents Dark mode separately from Incognito.
Should colour alone identify the session type?
No. Inspect the actual browser context.
