Minutiae: Color Codes for "Clean" and "Program" SDI

Perhaps a bit late to be asking this question but is there any generally accepted color coding for various types of SDI video signals?

E.g. in a project that I designed and recently finished installing most rooms have press/courtesy/house/whatever you want to call them SDI outputs for "Program" (e.g. with CG and embedded audio) and "Clean" (e.g. without CG and with embedded audio) adjacent to press audio mult plates.

For example:

We've been making an effort to apply color coding to anything that's not a 3-pin XLR used for normal 3-pin XLR purposes. I wound up specifying yellow for Program (harkening back to the days of composite video) and purple for Clean (because it's not a color we've used anywhere else)

Looking at it I found myself wondering -- a bit late -- if there is any standard documented anywhere for these things that I inadvertently thumbed my nose at that could make life easier for anyone visiting or if it's a bit of a catch-as-catch-can

Thoughts?
