Hi,
refining my proposal i tested this function to list about 7600 blueish
colors:
....
done
All random samples from this list yielded blueish background with
xterm -bg "$value" &
I hope there are not local spots of non-blue appearance.
It turned out that in my eyes high values of red can unblue ignificantly
higher values of blue to some pinkish magenta. Very low values of blue are
perceived as black, unless real black is there ifor comparison (then it's
midnight blue).
It's easy to forget that the human eye is sensitive to only a few photons of light.
At that scale and sensitivity, perception must be dominated by individual differences at a physical, neurological level.
So since we are all different from each other but grossly-similar at that macro level, we do not necessarily agree on color.
And since emotional perception often guides our neurological development, there is no hope of agreement :-)
Have a nice day :)
Schoenes Abendessen :-)
