Suppose I'm out somewhere, lookup and see a race in progress on a TV monitor. Then I note an outstanding unplaced run!

The only info I can get aside from the silk colours is (if I'm quick) the venue, and either race # and/or time.

The next day I can buy either todays or yesterdays newspaper and can see all the runners for that race but usually not the colours.

Is there somewhere I can say this is the 'horse name' what are it's (usual) colours?
