Modern Russians can differentiate between much more bluish colors, such as "sea wave", turquose, etc. I think it's the same with any people exposed to modern paints and hues so the effect is bound to be less important.

But they are not considered as separate spectral colors, whereas light blue is. So Russians have 7 colors in the rainbow.

I don't think that learning Russian will help your color perception in adult age and without being exposed to light blue paints, pyramid disks, toys, etc.

In fact, I'm not sure it will persist as much in the next generation of Russian children whose toys are usually made for world wide audience and don't set the light blue color out of myriad of hues.

Interesting point. I learned Russian as an adult for work -- and my colleagues always told me that Russians see the difference between the two blues the same way that we as English speakers see the difference between "pink" and "red". Pink is technically light red, but there is immense cultural significance invested in making the distinction.

Yep. Modern Russian children will have easier time telling pink from red than light blue from blue since they share the common material culture with the rest of world, but otherwise you are spot on.

Pink is another little color which appeared a short time ago and permanently extended our palette.

People from UK have 7 rainbow colours too - Red, Orange, Yellow, Green, Blue, Indigo, Violet.

The first Blue is like a cyan colour, the second indigo-blue is the colour of blue ink (a night-sky blue).

Then you've got two Russian blues already. That's exactly that.
