This isn't a religion vs science thread. If you have a question which is meant to disprove the bible/religion in general, there is another thread for it-

This thread is for the other kind of questions.

The bible isn't a text anyone can interpret how he/she understands it. The traditional way to explain the 2 biblical texts is different from your interpretation.
Your view of the text is simply not relevant, I'm not trying to offend, please understand:
Any religion should have a set of rules/ideas(the bible), and if the rules(or ideas) aren't clear, there should be someone/someway to explain what they mean. Otherwise, anyone would have his own idea of Judaism/Christianity/Islam, leading to a religion with thousands of different 'cults'.
Who interprets the rules? Every religion to itself, but WE, the Jews, give that AUTHORITY to the leading Rabbis of our time- a group of 120 respected people.
For example, we are ordered to not do any 'work' in Saturday. (Work= anything which shows the control of men over nature. it's a complex and wide topic in Judaism which can fill several books)
When the electricity was invented, Jews asked if using electric devices is considered 'work'.
It clearly wasn't mentioned in the bible, so the rabbis of the time had to decide, by reading the text and reviewing the unwritten traditions of Judaism. They concluded it is forbidden. Note, it doesn't matter if they were wrong in understanding that rule! Once the bible was given to us, it's up for humans to decide, according to the bible itself.
The rabbis decide not by guessing or rolling a dice- we have 13 methods of extracting information from the bible, and every decision MUST be based on the biblical text or the unwritten traditions- both we believe were given on Mt.Sinai. This includes ideas/concept like explaining the genesis story, they explain it by using a set of rules and rely on the tradition or the biblical text- all three originate from G-D himself. So, the system isn't fallible. Not only that, but the 120 rabbis vote, and the rule is decided by the majority. This system is reliable, and even if it makes a mistake, G-D himself tells us to obey anyway. I guess it's because the uniformity of the religion is more important than breaking a single rule.

I merged my reply to you with Captain Murphey's.
I'll add that kahena was not accepted by the majority of Jews, therefore he wouldn't be accepted as a member in a 'modern Sanhedrin'. Even if he did, there would be 119 people voting against his rules, and they wouldn't be accepted.
Obviously, the Sanhedrin doesn't decide about colors, but about religious issues. The left and right were an allegory to religious mistake/ religious truth.
