Alpha blending in Color.Darken and Color.Lighten

[Zelyutin]

Hi!

I've found interesting thing about Color.Darken() and .Lighten()
If i use the color like this: new Color(153, 173, 136, 60), that has alpha 60, and will use, for example, .Darken(), it will be less transparent because .Darken mixes the color with Black that has 255 alpha.

Does it really should work this way?
In my opinion, dimming and lightening shouldn't affect alpha channel

Maybe, there should be a parameter, at least, like [bool blendAlpha = false] that will allow to define whether we want to blend it or not
It's false by default because, as I think, most of cases will be without blending 🙂
Or maybe, it will be better to create separate function for alpha changing/blending.
