In your website, you stated that FD&C Yellow #6 is halal. How about Yellow #5 and Blue #1?
We contacted the FDA (Food and Drug Administration). Here is the reply we got:
The color additives FD&C Yellow No. 5 & Blue No. 1 are synthesized primarily
from petroleum-based chemicals.

There is no problem with FD-&-C Yellow No. 5 and Blue No. 1.
