Do You See What I See?

Fascinating.

When they show the green color circle fullscreen I couldn't see a difference--but when they showed a picture of the color circle on the monitor--I could see it right away.

Also, I wonder if the Himba have a form of hereditary blue/green color blindness.

I think people who work with colour regularly, such as graphic designers, would rapidly distinguish the odd colour out in the test, as it seems to be a question of value and intensity. My guess is that the Himba culture's colour vocabulary is based on one (or both) of these aspects instead of the more habitual approach based on hue.

I wonder how they would see @Zifnab's profile picture...

(As a graphic Designer...)
I noticed the difference on both variations immediately, although the green/green variation were very similar.

I was surprised they couldn't decipher the variation in the blue/green scenario.

I don't think they have a "hereditary" colour blindness to blues as suggested above by Boise_Lib but a "learned" blindness as discussed in the study. Because they have a more limited category selection for classifying the differences, their brains meld the grouped colours as the same and their brains simply record them as being the same thing.

A variation of this study would be to develop a category structure which uses more categories than our norm and raise a study group of children using that new structure. The brains of these children would categorize and identify differently and possibly educated their brains to see a wider difference of colours within the spectrum. (Of course this would be next to impossible, as the children would need to be segregated from all of society and only exposed to people who could emulate the new proposed category system - something which may seem as abusive to a child's freedom of being).

I remember first year of art school where we had to unlearn all we thought we knew about colour and relearn about the nuances in colours that we were never exposed to as a non-artist.

There are the hues
Primary: red, blue, yellow (white and black)
Secondary: orange, purple, green
Tertiary: red-orange, red-blue, yellow-blue, yellow-green ect.
Or even further - Quad-clours: red-red-blue or yellow-yellow-green

The complements: colours the appear on complete opposite sides of the colour wheel.
red compliments green, yellow complements purple, orange complements blue

And then the variations:

Intensity: Intensity can only be controled by the purity of the pigment being used. You can never increase the intensity of a colour, you can only decrease it by the means of combining it with any other pigment. The reason why artists pay premium prices for pure colours such as cadmium.
Value: colour changes made when mixing with various degrees of complement colours - mixing red with green, yellow with purple, mixing orange with blue.
Shade: colour changes made when mixing with various degrees of white (tints) or black (shades) to a hue. Black creating low values, white creating high values.
Coverage: Opaque vs. transparent/translucent applications

Using this structure, all the colour terms an average person uses now means nothing to me. words such as teal, brown, periwinkle etc.

These colours can now be described using a more precise system which includes a higher degree of variation..
Brown: low-intensity, low-value, red-brown.
Auqa: high-intensity, high-value, blue-green

OK class dismissed... There will be no test on today's lesson
