It is possible to have an array for color without this a[0].
a[0] has a unique meaning in AFL, we can not change it [and there is
no reason to change it]
It is better to ask your specific question in details [if possible],
I have no doubt we shall find a solution.
BTW, the convex/concave thread is not over yet, IŽll be back when
some theories give some money, this is the point I feel good.
Thank you for your analytic reply.
