Actually, on a closer examination, Mail's Help Panel text color gets dithered on Color Station. There are actually two kinds of pixels (RGB) = (51, 68, 136) and (RGB) = (51, 68, 153). The former gives B=0.5333 and the latter gives 0.6. So, it's not a 12-bit pure color. You've got to pick the color on a NeXTdimension to get the correct information. But there are more pixels of the latter in a unit area, though :-> -- Izumi Ohzawa [ $@Bg_78^=;(J ] USMail: University of California, 360 Minor Hall, Berkeley, CA 94720 Telephone: (510) 642-6440 Fax: (510) 642-3323 Internet: izumi@pinoko.berkeley.edu (NeXTMail OK)
