Still no luck, not even with memcpy.

There's even more mystery as I printed out the original static 
immutable array's content, which is different from the 
non-immutable one. Instead of the 32bit hex value of the given 
color in the format of "0x00000000", I get 
"immutable(Color)(#{overlap raw, colors})". This might be a bug.
