In Komodo X, the default color picker got some improvements, but it still does not support RGBA. (the preview popup supports it, but you can’t adjust the transparency with the picker itself)

@babobski solved that problem. His RGBA Colorpicker is based on PitPik colorPicker.

It’s very powerful! The most useful feature is adjusting transparency of current color with a slider. However, there are a lot of other things you may find useful, but I don’t find them useful for me.

Note

It replaces the default color picker and there’s no way to change between them. If you want to restore the default color picker, just remove this one and restart Komodo.
