I found a set of Gnome icon themes called ''Gnome-Colors'' in the Ubuntu Software Center.I have never changed icons before.Is there any way of making Ubuntu unstable if I install those icons.Or does it make resource usage higher?
It won't make any difference to performance or resource useage. Installing will just add the themes to your /usr/share/icons directory and so appear in your gnome icon theme settings. They are quite attractive, I often use the blue brave theme, go for it.
Right click on desktop, click customize on your selected theme, click install and point it to the icon archive.
Oh! I chose the green Gnome Wise.It is wonderful.It reminds me The previous Mint installation.The pink one is good too.
cet they dont take memory but if you install emerald theme's they bit heavy on system rest are pretty ok this site is full of wallpaper theme icons themes ............etc you can check it out if you like http://gnome-look.org/
