Yeah, racingandsports also has a good results service with all the horses listed from 1st to last. They don't list the colours though.

But looking at another site, I struggled to find a horse with darkish red colours which finished 5th or 6th. Command Raider was in cerise and finished 9th and Colourband was in Orange and finished 7th. Could it have been one of those? Or could you have the wrong race?
