Better background color

[SakibShahariar]

So, as the title suggests, we are basically using color0 as background color. In the color-scheme, color0 is the most darkest color and most of the time it's black or blackish. I suggest using the most used color of the wallpaper and then make it more dark.

i think the background color is color8 but hellwall generates color8 way too dark,

Oh, yeah color, but still it's quite dark for many wallpapers.
