Colored coins were a neat idea but completely impractical in practice. Hence, why they never took off. Bitcoin script is far too limiting to build expansive applications on.
This is plain false. It says so in big letters, right at the top of their website:

>Bitcoin script is far too limiting to build expansive applications on.
My original point was that weak smart contract features on Bitcoin motivated Ethereum's creation (Vitalik's name is on the Colored Coins whitepaper). This is in contrast to GGP's proposition that Ethereum had underrated novelty.

There were tokens (Colored Coins) and Dexs (Omni) running on Bitcoin before ETH was launched.
