I use kcolorchooser v2.0.0 under kubuntu 18, small and usefull app.
It has usefull feature : if I paste color in format “#3f5e5d” on the app this
color is set as current : https://prnt.sc/useqcq

1) But I paste color in format “246647” - it does not work . It demand first ‘#’ char.
A small issue, but can it be done automatically?

2) Also I would like paring color in format like :"rgba(0, 255, 9);"
3) Also i need for given color select best gradient color.

Has kubuntu apps like that ?
