I learned English at a young age, and I still think of "red" and "pink" as fundamentally distinct. I think I was taught at some point that pink was "light red" but it seemed weird at the time (when I was a kid) and it never sank in viscerally. They still feel like distinct colors—just like "red" and "orange" are distinct.

I think this is really similar to the two blues in Russian. Interestingly, while I grew up speaking Russian, I learned English at a young-enough age that I actually find the distinction between the two blues a bit confusing at time—I know about it, obviously, but it actually feels less strong than the distinction between red and pink. But that's just me with my weird upbringing :).
