+This folder contains the gimp source file for the palette icon of the 
+"colorpalette" component.
+
+The icons with appended _150 and _200 are magnifited with respect to the
+icons without appended number by factors 150% and 200%, respectively; they are 
+used for screens at higher resolutions.
+
+The icon is a slightly modified version of the icon provided with the package
+originally (source unclear).
