It works for me: https://run.dlang.io/gist/473b0021487275751accaebeb00be05c-- Bastiaan
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.
