#316 Option --back ignored

[Lew_Rockwell_Fan]

All of these produce plain black backgrund for me, under Openbox in Ubuntu 18.04:

yad --center --back=#770000 --text=hi
yad --center --back="#770000" --text=hi
yad --center --back=red --text=hi
yad --center --back=RED --text=hi

This issue is the same in PClinuxOS, aka pclos, which is in the Mandrake family, so it is not specific to Ubuntu or even Debian family distros. I'm still using plain Openbox as a DE though so it could be OB specific. I'd really like to work around this or fix it. I tried using --theme & --gtkrc for the same end result but they didn't work either. Is this project still maintained?
