i have 3 LP picture discs. 2 i bought brand new, 1 used. of the 3, one sounds amazing. the other 2 are noisy as hell. i don't buy them anymore, i just buy the regular LP counterpart which is usually cheaper too.
as for colored vinyl, i don't see how that can effect anything. as i type this im playing a double LP, 1 is plain black, the other is a creamy white. no difference, both are quiet and excellent.
from now on, all i buy is plain vinyl, no more picture discs for me, unless its cheap/rare there nice decoration, or to show off. ha
but i won't pass on a record because its yellow, or red, or see thru green, those all sound the same as black to me.
