Raid Difficulty Scaling System

Here's how the difficulty mechanism operates: each difficulty level is represented by a unique color taken from a gradient. This chosen color not only serves as the visual identifier for that difficulty but also influences the lighting and shading on other in-game elements associated with that particular difficulty setting. 

I thought about this mechanism for a long time, since there can be a different number of cards, and the gradient is always the same. As a result, together with the programmer, we managed to implement this in Unity.
