By chance spotted another colored machine in a black and white movie. Any typewriter that isn't black does of course stand out, even in a monochrome film.
This fairly clearly is a two-tone Remington Portable number 3.
Near impossible to determine the color-scheme, but the character closely examining the typeface in the scene is (clearly) Charlie Chan. The typeface does play a role in the story, identifying the machine where an important note was written.
This scene is from the '35 movie 'Charlie Chan in Egypt'. Whilst most of the Charlie Chan movies are fairly decent, simple whodunnits that are still quite watchable, this instalment in the series is a bit more dated than most. Despite its generous rating on IMDb, I would say this one hasn't aged well. The far-fetched story, the acting and the cringeworthy performance of 'Snowshoes' likely make the film unpalatable to modern audiences. It all does make it a product of its era.
Let's just say that there are better Charlie Chan movies to watch today.
(Even if they're without any sightings :)
