What is the opinion of Reddit about the
Taihao 140 Key PBT Double Shot Backlit Keycap Set – Deep The Forest (Blue)?

It’s hard to tell about just how deep the blue is, especially since most of the shots are trying to showcase the keycaps with a backlight.

There’s an Amazon user who gives a review of them here, and includes a picture of them:

He describes the alphas as a deep steel blue. Not sure how dark that makes them. I’m not good with colors, but I assume it’s a dark blue, lighter than Navy.
