TouchEffect.SetColor(view, Color.Red);
If effect doesn't work, try wrap view with ContentView and add effect to wrapper.
Add command to views.

View with borders, corner radius and clipping to bounds. View based on ContentView, you can specify child through Content property.

Why view, not effect like other features? Firstly I planned to do this. For iOS there are no problems, but for Android for clipping to rounded corners need override DispatchDraw from native view, that isn't possible from effect.
Configs and helpers for effects.
|Property|Type|Value type|Default|Description| |------------|------------|------------|------------|------------| |AutoChildrenInputTransparent|usual static|bool|True|Set ChildrenInputTransparent automatically for views with TouchEffect or Command. If value is True you DON'T need manually configure ChildrenInputTransparent. | |ChildrenInputTransparent|bindable attached|bool|False|If you use TouchEffect or Commands for Layout (Grid, StackLayout, etc.) and EffectsConfig.AutoChildrenInputTransparent is False you have to set this parameter to True otherwise in Android layout's children will overlaps these effects. Also you can set
InputTransparent = Truefor each children (EXCEPT views using any effect) manually.|
