Snow free, non deserted vegetated land appears green, greenish or brownish in the Snow RGB images depending on the (solar and satellite) viewing angles, the surface type, and the type, and the development of the green vegetation. Bare soil may appear slightly bluish (see the image on the left side).
In the image below, most of European land is snow free. If there is snow on the ground, the snowy areas appear red- orange: see for example the Alps, Pyrenean and Carpathian Mountains.
In the ‘real’ winter months at mid latitudes (when this image is most often used) land appears mostly greenish, like in the image below taken in January.
Explanation of the colours of non deserted snow free land (see also the recipe on the left side):
The resulting colour depends on the relative magnitudes of the colour components.
• For vegetated area the blue component is low. The land appears green or greenish brown.
-------> Wintertime (with less vegetation and lower solar elevations) the land appears typically green, forests may appear brownish.
-------> In other seasons the red and green signals are often comparably strong and so the land appears more often brownish (usually with green tones).
• For bare soil area the blue component may become slightly higher than the other two components, in these cases the land may appear greyish blue.
