The visual image on the website is a composed image. The satellite image is a combination of 3 visual spectral channels, each of which was assigned a specific colour red, blue or green. This technique allows for marking the contrast between different cloud types through colours. This combination accentuates the contrast between water droplets and ice crystals.
These images are useful for distinguishing high clouds from low clouds, localising storm clouds (CB's) and observing snow fields.
