In most parts of Spain red was the colour used for prickings. And continues being. In other parts of Spain, yellow has been used, also green.
Nowadays, it seems that most lacers continue using red or orange. But I myself use blue, as I find it more relaxing for my eyes. I started using blue after a German lacer told me. I suppose that, at the very beginning, lacers didn't think so much whether the chosen colour was good for their eyes or not. They used some natural product they had at hand to dye the cardboard. It's just a guessing... Regards from a Spanish lacer, Antje González - To unsubscribe send email to majord...@arachne.com containing the line: unsubscribe lace y...@address.here.
