Standard Color Coding for Dosing Pump tubing?

[joe-ejs]

Hello,

I just bought some color silicone tubing to replace clear tubing for my Alkalinity and Calcium Dosers, and eventually a doser for Trace Elements, etc. I was wondering if there is a recognized standard for what color tubing is for Alk and what color for Calcium. Just wondering before I replace my clear tubing with the color lines. I have labeled my reservoirs so I know which is which liquid, but thought I would ask.

Thanks

I have these stickers on my dosers and containers.

So I would match the red yellow and orange tubing to the coordinating sticker.
