Conceptually, you are right and agree with you, but appearance impacts perception and the brand. As a buyer, appearance matters. People don't buy cars they think are ugly. Appearance plays a role in every thing and I've heard dealers say they don't like the green label. Personally, the first time I felt and looked at a CSG slab I liked it way better than a PSA slab. Feels more solid, more clear... I liked it!
Regardless of what you and I think about it ... I heard the parent company CEO say they are changing the label and I hope it positively impacts the value of the "old" labels.
