+1 @ variability in perception.
I literally had to get a paint swatch to put next to my house to get someone to believe me when I told them what color it was. At the time it was a pale green, yet they insisted it was beige. The funny thing is that they are not color blind and have a great eye for color in their own artistic endeavors.
I've since painted the house a darker green ... some days it ranges from a middle green to a hunter green depending on the variability of the sun's. It really is perceived as a significantly different color, even though it never changes.
Between the viewer and the environment ... chasing reality with uncontrolled variables gets to be a bit of "wild goose chase" at times. For me, I suppose I'm more sensitive to seeing the blue's than most, since so few people seem to notice/care @ the blue/cyanic casts from the overhead sky the way I do.
There was a link to a color detection test a while back (alt forum a few years ago) that revealed some interesting results as various FM members reported their results. Mostly guys taking the test iirc, but even within that gender, the variability was noted.
