Ugh ogh... So with your example, you would "calibrate" everything to
look good only in your room with reddish walls.
I didn't mean everything, just the monitor.
On a printed picture medium gray is RGB 128,128,128 or CMYK 0%,0%,0%,50%
The printed picture reflects the existing light so if it is printed
right it look OK everywhere.
On a picture saved on disk gray should also be RGB 128,128,128 if you
want it to be acurate
(not so if the subject of the picture is more the environment than
specific things that appear on it)
A monitor emits light so it does not color-adjust to the environment,
you have to do that yourself
(visually setting up several tones of neutral gray so that they look
gray to your eyes, with software that allows you to do that or, more
acuratelly, by knowing or measuring the environment light as Rob
Studdert has said)
Only after doing that you can use your monitor as a tool to produce
color correct work.
(...and my walls are white)
That's fine if thath's
the _only_ place you will _ever_ see your photographs, and never
print them... That's good for you? You will edit your originals to
look good _only_ in that one room? Never print them? Never share them?
Monitor calibration does not change photos you save or print, it's like
a color correction filter you put in front of the display, it's for your
eyes only.
