missing colors 

I tried to compile your ggplotd on my project directory.  It failed to build because of "ggplotd/colourspace.d(8): Error: module `hsx` is in file 'std/experimental/color/hsx.d' which cannot be read" I checked directory usr/include/d/std/experimental/ ......and there is no folder color.  Be careful using color / colour.
How do I get color folder?
