Thank you for the tip. I'm a little worried about my personal settings. I see it has an option -def that can be used to restore the default attributes. Also the documentation is limited.

Thanks! This was exactly what I was looking for. Here's what I did : in https://git.reviewboard.kde.org/r/103055/
I discovered where xsetroot is called by /usr/bin/startkde and changed
xsetroot -solid "#103D77"
xsetroot -solid "#043824"
Talk about a stickler for details.
Thanks for this wonderful forum!

Many thanks!! This answers accurately my initial request about changing the login background when no image is selected. The default background, a blueish solid color, is different from the blue color set in startkde that flashes for a few tenths of a sec after starting KDE and before any splash screen is displayed. So, in fact both answers are needed for a smooth transition from the login screen to the KDE desktop, if you select no background image. Note that, with the gnome environment there is no blue flash at login, apparently because no call to xsetroot is performed.
