Some sellers have certain colored tops and each one maybe known for certain affects. That is only for sellers who have them listed for long periods while using the same supplier. An example would be TP and his black and grey tops. It still means very little as each person reacts differently. Just pick a sponsor with a good rep and don't worry about colored tops.
It really depends on who your getting them from. Some pick certain color tops to promote there brand. All of them SHOULD be 191aa if you use a trust worthy supplier.
