I have a bunch of sets(4) of Team Orion foam tires, not dried out yet, looking for someone who can enlighten me as to the colour scheme used by Orion? I have yellow, red, pink, purple etc and need to know which order they go, hard to soft. This would be easy if I owned a dourometer, but do not, hence the question for all you onroad guys, thanks.

Calandra has the most comprehensive description of foam tyres, including cross referencing all the colours and shore ratings.

For something a bit simpler but doesn't include all the modern tyre colours, there's this old guide from Trinity

Thank you Terry. I have been looking for quite awhile. When I really gave the issue some thought, this site and people like Terry make this the best site for finding out just about everything RC. Thank you.
