    I would prefer a label 'Class 1 system' rather than the sharpie blackout.

    I would encourage you to pick obvious colors that are not used in your building.
    There was a tenancy to use grey and purple which I have seen mistakenly connected to neutrals.
    I spec yellow and purple.
    Cheers
    Yellow is commonly used as one of the 277/480 colors, just like the grey often is for the 277 neutral.
    I live for today, I'm just a day behind.

    Sometimes I feel like I am running out of colors.
