Do you show the slides at lab meetings? Not going to cut it. The types of numerical color descriptions discussed below are color models, while the color spaces are sets of colors.
The color model value is mapped onto the color spaces so that it appears the same in all situations. Things are more complicated than that. Rarely do different computer monitors display the same colors.

One of the most common sources of multi-channel data is from immunofluorescence microscopy, where signals from multiple fluors are captured and recorded on separate channels. Each channel can be presented in a separate image or in a single image.
