I am investigating the idea, and i saw how it seems it's the transactions that are colored. Can someone explain this choice to me?
What choice?
the way I see it, you can either color specific outputs or you can have a whole different type of token running alongside normal ones.
again if i am wrong , please let me know.
Yes. The motivation is to allow other tokens to enter the market, but not requiring you to get enough nodes and miners to secure the network.
Using the OP_RETURN field, you can add arbitary data, that represents your coin.
