Colored beds don't have a color state so they can't be placed via /setblock
or /fill

What I mean is that coloreds beds don't have the color state at all, for example, wool have it : /setblock ~ ~ ~ wool color=blue but if we do /setblock ~ ~ ~ bed color=blue it doesn't work because beds don't have this state
