Is there a standard color code for drill rod or does that vary by supplier or manufacture?

It's usually Yellow but It does vary by manufacture

good question and got me curious as I didn't know the answer offhand.

Anyway, it looks like it varies by manufacturer, here are 2 separate makers:

the reason I ask is that I work at a power plant and they have some drill rod that a guy got for me. The smaller rod has a yellow end and the larger diameter rod is red. He did not know what material it was as far as O-1, A-2 ect. I was trying to find out what the type it is

I asked on rec.crafts.metalworking about color marking metal:

I'm not a machinist and don't know what colors are what .I obtained these from a machine shop

and they definitely knew what was what .

I have M2 Steel which is Red coded , I have D-2 Drill rod which is White coded .
