Default Inside the Shell Metrics
I asked myself what SHMetric stands for?

Quote:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Metric]
"SHMetric"=hex:5F,00,00,00,05,00,00,00,00,00,00,00 ,02,00,00,00,00,00,00,00,64,00,00,00
"DefSHMetric"=hex:5F,00,00,00,05,00,00,00,00,00,00 ,00,02,00,00,00,00,00,00,00,64,00,00,00
After randomly changing and a lota soft reboots I found that
SHMetric"=hex:5F,00,00,00,05,00,00,00,00,00,00,00,12,00,00,00,00,00,00,00,64,00,00,00

5F (dec 95) looks like the X value for the Office background gradient change
(like in Tasks)
the 12 changes the background line height (take font height) to get a nice effect.

Perhaps the colors used in the Calendar are also hidden in here.

Perhaps you can experiment with me and post your results here.

Cheers
