space" the colors as measure by DigitalColor Meter is exactly the same
RGB-triple you specify in Vim's ":hi" command.
While this may seem desirable I'm not really sure that it is. Reading
Apple's developer documents  it would seem a bad idea to use a
device-dependent color space (e.g. if you have two monitors the colors
will match better with a calibrated color space). It seems more
appropriate that anybody who thinks the colors are "too bright" or
"too washed out" should instead calibrate their monitors. That's not
the final word on this issue -- I'm just reporting my findings. I'd
like to hear more opinions on this.
To conclude: I'd consider changing to a device-dependent color space
(i.e. so that rgb values measured with DigitalColor Meter matches the
values specified in Vim), but before doing so I need an informed
argument as to why this is preferable over using a calibrated color
space (which tries to ensure that the colors look the same on
whichever device is attached).
