Silver UI is a mod for Kingdom Come: Deliverance that recolors the player healthbar, stamina bar, and other elements of the UI to make it look more like a vial.

As you can see in the screenshots, the player healthbar is recoloured to be more like a vial, and the other elements of the UI are changed to match it. This is done by changing the background color of the bars to be more similar to a vial, and by changing the color of the healthbar when the player is not hurt.

The idea of this mod is to change the look of the game so that it is more like a typical RPG. It is not designed to change the gameplay, so you will not have to make any changes to the game.
