the obligatory 0.0001 transaction fee is a bit of a pita for playing around with these colored coins,
which are only 0.000006 each
0.0001 BTC is only four and a half cents ($0.045). The transaction fee is a deterrent from creating a bunch of spam transactions, so it is a very good thing.
In a practical setting, the value of the "color" transferred should be much larger than the transaction fee. The fact that only 6 bits actually got sent is not the point. The point was to transfer ownership of the digital assets.
It typically costs over $100 to transfer assets such as shares between brokerage accounts--that's at least 2000 times more expensive than transferring shares using open-assets.
