A single color object and a transparency gradient,
covering part of the underlying object.
The gradient can be dynamically adjusted, made
more transparent by moving the white square or
more opaque by moving the black square.
An object with a color gradient, completely
covering another object.
The gradient is adjusted dynamically by moving
the squares – the color of the square relating to
the increase or decrease in that color.
An object with both color and transparency
gradients, partly covering the underlying object.
