Weird icon in Dolphin

Just installed 12.1 KDE,icon theme is nice Oxygen icon in system,but Dolphin showing different icon,something like ugly blue color Gnome icon,what happened? How to get Oxygen icon works in Dolphin?

The Oxygen icons were always Blue
They do have a dark stripe now

No,I have 11.4 before this,the Oxygen icon was nice,but now I’m pretty sure it is NOT Oxygen icon,all the folder icon in Dolphin change to something like old time gnome tango or high color icon…

You better do a screenshot then

…this is suck… >:)

That’s how it is now
Guess you could look around at kde-look

Oxygen Old (before 4.6.2)
