Can coloured coins be given to miners? Does the coloured coins spec (or an informal convention amongst its implementers) track coloured coins left to the miner of a transaction's block in the standard manner?

Obviously the miner would have to be running a coloured-coin-friendly mining implementation, but I was wondering if anyone knows whether there is intended to be a way for a coloured-coin-recognising miner to do this.

The coloured coin spec document at

https://github.com/killerstorm/colored-coin-tools/blob/master/colors.md

Makes no mention of mining except to say that


  Fee[s] should be paid using uncolored coins. If it is absolutely necessary to pay [a] fee with colored coins, that color should go...last.


Is it intended that in this scenario the miner can "collect" the coins while retaining their colour?
Although it's not covered by the specification, it seems logical to match all transaction fees (in the order in which the transactions appear in the block) against the block reward the same way other transactions are matched. The leaves only whether the block reward comes before or after the transaction fees. I think it makes the most sense to put the block reward after the transaction fees, since the block reward will always consist of uncolored coins (unless someone "pre-colors" them, which seems strange), and the convention is that uncolored coins go last.
