Multicolored shadows

I think that swayfx would benefit from having the option for different colors. e.g you could have a shadow color for the focused window, and inactive windows could have a seperate color as well. this could potentially also be combined with the upcoming fade animation feature, e.g the shadow color will fade from active to inactive as the focus changes. thanks for reading this, i appreciate your time.
