Leather armor pieces have darker colors when on hand or dropped

When you have a piece of leather armor in hands (either a leather helmet, tunic, pants or boots), it shows to have a more darker color than shown in the hotbar. This also happens when you drop them.
However, the leather helmet, pants and boots kept the original color in their secondary color part.

Here's a video to show how the leather armor color bug looks like:
