Setting scrollbar colors

[Tim Johnson]

I'm using emacs on ubuntu 14.04 with the follow settings
version :
24.3.1 (x86_64-pc-linux-gnu, GTK+ Version 3.10.7)

system-configuration-options
" '--build' 'x86_64-linux-gnu' '--build' 'x86_64-linux-gnu'
'--prefix=/usr' '--sharedstatedir=/var/lib' '--libexecdir=/usr/lib'
'--localstatedir=/var/lib' '--infodir=/usr/share/info'
'--mandir=/usr/share/man' '--with-pop=yes'
'--enable-locallisppath=/etc/emacs24:/etc/emacs:/usr/local/share/emacs/24.3/site-lisp:/usr/local/share/emacs/site-lisp:/usr/share/emacs/24.3/site-lisp:/usr/share/emacs/site-lisp'
'--with-crt-dir=/usr/lib/x86_64-linux-gnu' '--with-x=yes'
'--with-x-toolkit=gtk3' '--with-toolkit-scroll-bars'
'build_alias=x86_64-linux-gnu' 'CFLAGS=-g -O2 -fstack-protector
--param=ssp-buffer-size=4 -Wformat -Werror=format-security -Wall'
'LDFLAGS=-Wl,-Bsymbolic-functions -Wl,-z,relro'
'CPPFLAGS=-D_FORTIFY_SOURCE=2'"

I'm not able to set scrollbar colors though either the native
customizing of the face or through .Xdefaults or .Xresources.

Since the toolbar widget and the 'trough' are almost the same color,
it makes it very hard to read in most lighting circumstance.

Any ideas would be appreciated
thanks
