Hi,
I am trying to calculate the number of pixels using a histogram
specifically for 3 colors(white,black and green) in a image (256
colors).
I have modified the color palette for the image so that the background
is white and the dark colors are black and the light green remains the
same.
I am unable to interpret the results as indicated by the histogram.
I have uploaded the pictures.

Would appreciate any help in how to calculate the number of pixels of
white, black and green.
Thanks.
