Hi Dhaval, thanks for reporting this issue. Seem to we have problem with rgba color in src/plugins/option-color/CorlorpickerControl.js

For some reason alpha is ignoring in rgba color. That's the reason why we have black background in shapes, instead of black with full transparency when choose transparent in color picker.

ColorpickerControl.prototype.TRANSPARENT = 'rgba(0, 0, 0, 0)';

It would be nice if someone could help to fix this bug.

Hi guys!
In the file "Color.js" , when the event "_onColorSelected" is fired, "alpha" of selected color is replaced (in _hexToRgba function) by opacity value from "opacityControl", which is one when the opacity control is hidden (generally). Then the "transparent" (rgba(0,0,0,0)) turn black (rgba(0,0,0,1)).

Suggestions to fix it:

• Avoid to change alpha when:
  • opacity control is hidden
  • "selectedColor" is "transparent"
  • ...

I fixed it avoiding changing alpha when the opacity control is hidden (definitely not the most elegant solution).

See you!
