The graying effect should be configurable

[bilowik]

I somehow became blind to the effect and forgot all about it.

Could actually configure to be able to mix any color.

To avoid over-complicated the shader, and potential performance issues, should probably split the shader into 3?

• Base
• Grayified
• Custom Color

What if both gray and custom color are specified? Maybe custom_color should take precedence.

Gonna leave this to just enabling/disabling gray, will make a future issue to track this.
