Converters

 Synfig Studio offers a range of converters, which are very powerful

tools one can use when animating. In effect, converter is a bit of a misnomer

because one is here given an opportunity to add functionality. It might

take a while to assess everything one might do, but one can have fun along the way.

Important to remember, the conversion is not on the object in the layers panel

but on one of its properties.

 Below, I ask for convert on color and can change the colors of the gradient

without fiddling with anything (at frame 96). I also changed the opacity of the

image at frame 48 down to .6. At 96, I put it back to 1.000. Smooth...

Just right-click on color and choose convert.
