The icl8 (and the icl4 and icl2) describe an icon of a specific bit depth.
The icl8 uses 8 bits for every pixel, the icl4 uses 4 bits for each pixel,
etc.  In System 7.0, the Finder will use color icons ala the ColorFinder
INIT.  To draw the icons, it will use the icon resource corresponding to the
current bit depth of the monitor i.e. if the monitor is set at 8-bits (256
colors) is will use the icl8.  This is done for speed.  It is faster to draw
the icon if the bit depths match.
