Nope-- but it is easy to figure out;  launch Mail, open Help, click  
Format->Font->Colors...., grab the magnifying glass, grab a chunk of blue,  
switch to the RGB color picker and read the numbers:

(R 51, G 68, B 136)

On a related topic, does anyone have a tiff or EPS file that contains
every color that is both 12-bit pure and maps to a pure 2 bit gray-
scale value?  This would make a useful color panel palette.

I posted a couple of EPS files here a while ago that generate every 12
bit pure color, so these could be used for ideas if no one has
undertaken this pursuit.

please post or email if you have such a beast.

There's no connection between the blue color's rgb values and the  
pure light gray that appears on a monochrome display.  The .tiff  
files that produce these graphic elements each contain two separate  
TIFF images:

# tiffutil -info 3PixelRule.tiff

  Image Width: 359 Image Length: 3
  Resolution: 72, 72
  Resolution Unit: pixels/inch
  Bits/Sample: 8
  Compression Scheme: none
  Photometric Interpretation: RGB color
  Samples/Pixel: 3
  Number of Strips: 1
  Planar Configuration: Not planar

I'd  like  to add a value of  10 to all R values  of a TIFF file.  Or x to all
[RGB] values. And a second utility to map all  x values into a  given y value,
only  for one color or  for all three colors.

Is there a  utility  that does this?
