The value in the gimp histogram is calculated as the maximum of the red,

three color channels?
We discussed this when I was fixing the histogram for 1.2.x BRANCH (btw,
did that fix go into 1.2.1, or did it just rot? Maybe I should look for
myself) and I can't remember what the arguments were for leaving it as
it is, but that's what we decided to do in 1.2 at least.
Well, max (r,g,b) is the correct formula for calculating the value of a
color (assuming that value corresponds to the V in HSV). The average of the
three channels is a somewhat useless number, but it might make sense to add
intensity (mostly defined as 0.3 r + 0.59 g + 0.11 b) as an option.
