Except when they’re stupid too. In the tutorial area of Horizon: Zero Dawn they have you climb a wall. The handholds are marked with white and yellow.

Except it’s evening in game and the color grading effect makes everything a shade of orange. The colors aren’t distinguishable and the shapes of handholds are still new. Took me two hours to figure it out. I knew I had to climb the wall, but where to do it and where to go on the wall was a mystery.
