Does the sticker have a name as well? What year's the car?
In the MK1 sales brochure i have (circa 1978/9 i suppose) it has one yellow colour and it's 'Lemon Yellow B2B2', but your car is older than my brochure/my car, so i'm guessing the code you've got is right.
Wait for Pete Jones' reply, he'll know.
