Colors are enchanting and elusive. A multitude of color systems has been proposed
over a three-digits number of years - maybe more than the number of purposes that
they serve...
-
Everyone knows the additive RGB color system – we usually serve light-emitting IT
components like monitors with colors in that system. Here, we use c = (r, g, b) RGB
with r, g, bЄ [0,1] to describe a color c.
=
T
For printing, however, we usually use the subtractive CMY color system. The same
color c becomes c = (c, m, y) CMY (1-c, 1-m, 1-y) RGB Note how we
use subscripts to indicate with coordinate system the coordinates correspond to.
Explain, why it is not possible to find a linear transformation between RGB and CMY
coordinates.

You manage a chemical company with 2 warehouses. The following quantities of
Important Chemical A have arrived from an international supplier at 3 different
ports:
Chemical Available (L)
Port 1
Port 2
Port 3
