Gamut refers to the range of colors that can be reproduced. Color intensity
is not a term I'm familiar with, but I suspect you mean color saturation or
purity. That is only one dimension of color gamut. One way of defining a
color is in terms of hue, saturation, and brightness. Chromaticity diagrams
usually only show saturation and hue, brightness being a third dimension
extending out of the paper. But gamut is the three-dimensional volume of HSB
that a particular device or technology can present.
There is more to green than darkness and brightness. There is how much of
other colors are mixed in with it (the purity or saturation of the green)
while still giving the impression of the color green. Obviously a point is
reached where we can't decide (for example) whether the color is green or
cyan because of the amount of blue mixed in with it (taking within the RGB
domain). In fact you can have a considerable amount of red and blue mixed in
with green and it will still more or less look like green.
