There's one way to avoid the tricks of the brain: to match colour
patches. If you compare two colour patches you can determine how they
relate. That's what colour management is all about, isn't it ?:
reproducing the same colour on different devices, so that when compared,
they look the same.
In my company it is allowed to compare two colour patches, all within
the realm of colour management. But the comparison of a colour patch
with a colour in a picture is strictly forbidden. It's apples and pears.
A colour in a photo is not within the realm of colour management.
However, the reproduction of the photo is.
The trick we have to judge a colour in a picture is to hold a colour
patch in one hand, hold a photo representing an object in the same
colour in the other with some distance between the two. if then you have
the IDEA that both colours resemble, it's ok. But measuring will get you
nowhere.
btw: I heard yesterday that our colour tricks saved the Dutch city of
Arnhem millions of dollars because using our technology they were able
to avoid a bad choice of colours on a huge metal bridge over the river
Rhine. Obviously the local government was VERY pleased with it.
I will mention a short parable.......
