    current is color blind. just read the values.

    Bussman does talk about color coding their fuses a few times on the
    web site but I got tired of looking before I found the color code
    chart. I know there does seem to be a plan..

    color coding makes sense on parts that are so small the numbers would be
    tiny and parts that heat (like resisters) where the marking may burn.

    it also makes sense for automotive type fuses to be colored. the average
    user can more easily replace a red fuse with a red fuse and get it right.

    on large fuses there is plenty of room to indicate current, voltage, and
    type with no ambiguity.

    Bussman implies that less than qualified people may be installing
    fuses and it is easier to replace a red one with a red one.
    I think it is a similar intent to the type S adapters in plug fuse
    panels.
