I think 2J's is more of a nice lemony yellow. This thing...isn't.
There is also "Kansas Beige"...
Lemon Yellow
and Texas Yellow
I see a lot of Saturn Yellow Super Beetles...I find them a bit of an assault on the eyes.
Mine is Yukon Yellow (L 19 K)...
However, mine has faded quite a bit and is "now" what I consider a very pretty butter yellow. I'd just soon keep it that color, have it actually matched. But Steve is a purist and wants it put back to what the label says. "Yukon Gelb" as it says in German.
