Sorry to hear that the pink lake wasn´t actually pink when you came there but in fact, this is quite common with these salt pink lakes as their color depends on many factors. We saw some of these lakes in Mexico. They were not at their "pinkest" either but still some cool hues :)
Yes we will never know when the lake will have colour but even still it was very beautiful to visit. I'm sure in Mexico would be very beautiful as well :)
Thanks for your sharing @phortun and have a lovely weekend :)
