[OpenLayers-Users] kamap background tiles

[percy]

Yeah, I was hoping to understand the tiling mechanism better, because if 
I can get away just using the background color on the DIV, then it 
implies that I can free up some disk space by deleting a bunch of tiles 
that are just colored blue!

Thanks a bunch, though, I used an online color picker to turn my RGB 
triplet from the mapfile into a hex RGB, and Voila! my rivers are blue 
again. (background-color: #B6DAE1)

Cool.
