The colour variations in this image are very similar to those I see 
every day in my, and several others, neibourhood. The colour variation 
don't come only from the cooking temperature but also from the pigment 
used, and how well mixed in it was, and variations in the clay used.
Older houses have much more variation than recent ones reflecting both 
hovens having a more uniform temperature and improved mixing equipment.

Here again, I need to disagree with you. Most bricks I see every days 
are almost identical to those.
