What is "Alpha", "Delta", etc...?
I've heard about it, and I now need to use it. However, I don't know how to use it.
I'm trying to use the "Color3:lerp()" feature, which states
`Color3:lerp(Color3 goal, number alpha)
returns a Color3 interpolated between this Color3 and the goal by the fraction alpha`
But where it says number alpha I have no clue what to add. Please help me.

Alpha refers to a number between 0 and 1, essentially a percentage of the way through the transition. You will also find alpha in other cases such as in images when a pixel is transparent, it is said that it has an alpha channel.
Delta refers to the difference between two things. e.g., "delta time" in a rendering context usually refers to the time that has passed since the previous frame was rendered. Sometimes you will find a delta represented by a triangle, the Greek letter for delta. See More
