Hi,
In my shelf there is the HARP LE hardbound in dark red and next to it the HARP hardbounds in green. Therefore, as it would fit nicely colorwise and also because since SM:P it is the color I associate with "space books":
I would love to have a dark and saturated blue as the background color for the HARP.
And if possible please only one color, I was a bit disappointed by the RMCs where there is a strange brown stripe on the black background on the small side facing you when you put them in a shelf.
BR
