This Iceberg Looks Like Batman

Mr. Freeze* now has an equally icy opponent. This iceberg looks just like the Dark Knight spawned on a cold night in Crime Alley.

On another note, women cannot be color-blind and men cannot have super-color vision like some women. Whereas men will be color blind because they lack a third cone responding to the red range, women can have a fourth cone that bisects the red range and gives a richer spectrum of colors. Then there is achromatopsia which is the inability to see color and a really bad name for a baby girl.
Perhaps some of the difference is in the color-opponency cells in the occipital cortex and perhaps the associating of different colors. A part of me suspects women are trained by the culture to recognize a greater range of color names and men are basically not expected to. Wine-tasters also have a wider range of names for flavors, using terms like "earthy" that non-wine-tasters by and large don't use. I doubt the wide range of color names employed by women are innate. But like the wine-tasters, they learn to discriminate.
Even given all that, which is done to be fair, I think there might actually be some innate predilection, but devising a conclusive experiment for that is problematic.
@ Ryan S, women can also have colour blindness but it is quite uncommon. Colour blindness is carried on the X chromosome. If males inherit an X chromosome with the mutation it will be displayed in the phenotype. If women inherit 1, she will be a carrier, however if she inherits the mutation from both X chromosomes, it will be displayed in the phenotype.
Also, you have a point about gender differences in the vocabulary of colour:
"Stecklers' study in 1990 concluded that women's ability of naming colors is far more precise than men's and also they have a broader vocabulary for color names such as ecru, aquamarine, lavender, and mauve."

You are right, my mistake, color-blindness is a recessive allele on the X chromosome
