a The field of view shows different colors (hues) that depend on the topography of the specimen. b Each pixel in (a) gets a new easy-to-follow-color (green, blue, black) based on its original hue-value. c–g A moving cell stops, and its color changes from green to black, indicating that the original hue-value changes, suggesting that the topography of the sample is different due to the lack of liquid (time intervals from the first image are indicated in the other images). h–l A temporarily immobile cell starts moving, and its color changes from black to green, indicating that the original hue-value changes, suggesting that the topography of the sample is different due to the presence of liquid (time intervals from the first image are indicated in the other images).
