Look at the quality of those images of the ground in that video. Those blades are whirring around at super-high rates to provide lift in the Martian atmosphere and taking 30 pictures per second, but in each exposure you can clearly see the shadow of the blades with very little blurring. And with ambient solar brightness quite a bit lower than Earth's "full sunlight", too. Those are quality cameras.

- teraflop 5y agoThe first image, from the Perseverance rover's MastCam-Z, is at least as much "true color" as any ordinary camera. (That is, the precise color might be slightly off due to differences between the camera's sensitivity and your monitor's spectrum, but it should be pretty close.) The video from Ingenuity itself is taken by a black-and-white camera and has no color information.
