*as of 2011 the listing has been changed in the price guide to Windex Blue - this was done after comparing it side by side with insualtors listed as being sapphire and the color was shown to be very differnt8 This is a pic of the elusive Windex Blue CREB145. It obviously is not the same color as a sapphire blue HGCO CD 162/CD 145, but this is the CREB color designated as sapphire. Originally I had been calling mine Windex Blue until I tracked down the background on these pieces. Wondering if your CREB is Windex? Put it next to a Montreal CD 143 in the "normal" blue these 143's pieces come in. The two colors are very close.
