Tell us about the onions.  Did you plant one set to a hole or were they
bunching onions?  Did they bulb faster or slower?  I read somewhere that
onions like cool ground in which to bulb and warm air for green tops.  Or do
I have it backwards?  Also, did you happen to make a comparsion with the
unpainted cinder block and the painted ones?  The blocks are already grey
and absorbs lots of heat.  Plus, the concrete is rough, with many pits and
pockets to store heat.  I'd think painting the blocks would create a flat
surface that may reflect more heat on to plants during the day, but the flat
surface wouldn't have as much stored heat to release at night.  Just a
thought.  Please tell us more.
