False color facts for kids
False color (or false colour) refers to a group of color methods used to display recorded images in color. A false-color image is an image which shows an object in colors different from that which a true-colour photograph would show.
In addition, there is false color used for visualization of genuine data.
A photograph shot in color will show the colors in the picture as they appeared on the film, or to the sensor of a digital camera. This is known as true-color image. In a false color image, the color shown in the image does not correspond to the one the film or sensor recorded. In such an image, which is known as false color image, color is used for extra information.

Burns Cliff inside of Endurance crater on Mars. The color is approximate true color because, instead of the red spectral band, infrared was used. The result is a metameric failure in the color of the sky, which is slightly green in the image – had a human observer been present, then that person would have perceived the actual sky color to have a bit more orange in it. The Opportunity rover which captured this image does have a red filter, but it is often not used, due to the higher scientific value of images captured using the infrared band and the constraints of data transmission.
An image of Tasmania and surrounding waters using density slicing to show phytoplankton concentration. The ocean color as captured by the satellite image is mapped to seven colors: Yellow, orange and red indicate more phytoplankton, while light green, dark green, light blue and dark blue indicate less phytoplankton; land and clouds are depicted in different colors.
