I'm not entirely sure I understand what you're suggesting here. Do you
mean a selective area way to cook an image to grayscale, emphasizing
different color-tonal relationships depending on location in the
image?
not selective area, selective color relationships ...
what i'm envisioning is a tool which works on a higher level than having to
calculate or experiment with color mapping values; for example a user might
point to a pair of colors in the image, or an select area with a color
transition; the tool would then present grayscale versions of those colors so
the user could, in effect, adjust the contrast; do that in different parts of
the image, and the tool would then work out a mapping that would best achieve
the desired result
