true colour
<graphics> A system where the red, green, and blue components
of a colour are stored in display memory, as opposed to
storing logical colours and using a colour palette to
convert them to red, green, blue components.
The advantage of true colour over a palette is that it does
not restrict the range of colours which can be displayed on
screen simultaneously. For example, if eight bits are used to
store each component of each pixel then a total of 2^24
(about 17 million) different colours can be displayed at once
which would require a (very expensive) palette with 3 * 2^24
bytes (about 50 megabytes) of memory.
The disadvantage of true colour is that image transformations
which would normally be done by changing the palette must be
done to every pixel of the image which can be much slower.
Compare high colour.

Color image pipeline
Color Image Pipeline
An image pipeline or video pipeline is the set of components commonly used between an image source (such as a camera, a scanner, or the rendering engine in a computer game), and an image renderer (such as a television set, a computer screen, a computer printer or cinema screen), or for performing any intermediate digital image processing consisting of two or more separate processing blocks. An image/video pipeline may be implemented as computer software, in a digital signal processor, on an FPGA, or as fixed-function ASIC.
false colour
![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.](https://commons.wikimedia.org/wiki/Special:FilePath/Burns cliff.jpg?width=200 "Endurance crater]] on [[Mars]].
