You are talking about the grid in gschem with light background, do you?
I too have diffficultiy to see this grid with default settings of geda. It 
is barely visible on my setups (four desktops at home and at work). The 
slightly greyish background color does not help, too.

Unfortunately, there is no GUI way to set the colors. In default set-up of 
geda, the colors are read from the text file 
	$INSTALL/share/gEDA/gschem-colormap-lightbg  

I slightly teaked the color values in this file for better visibility. 
That is, make the background real white and grid lines a little darker. 
Since bad visibility affected all my desktops and my laptop too, I 
thought, it would make for a nice little patch. The patch got accepted but 
got reverted almost imediately. The following discussion did not reach 
consensus. I got told, that I use the wrong harware and should assume, I 
am the only one who feels the need for a change.

Anyway, this line in gschemrc will load localized colors instead of the 
default color map:
	(load (build-path (getenv "HOME") ".gEDA" "gschem-colors")) 

For this to work, you'd have to supply a tweaked colormap file 
	$HOME/.gEDA/gschem-colors
