  In accordance with ICEA publication S-80-576-2002, the colour code is composed of ten (10) distinctive colours to identify 25 pairs. Marking of each mate of the
primary conductor in a pair with the colour of that primary conductor is optional.
When cables of larger than 25 pairs are required, the core shall be assembled into 25-pair sub-units, each colour coded in accordance with ICEA publication
S-80-576. Cables with over 600 pairs shall have 25-pair binder groups combined into super units. These super units shall be wrapped with a solid colour
thread that follows the primary colour scheme of white, red, black, yellow and violet. Binder colour code integrity shall be maintained wherever cables are spliced.

  Pair Identification Colours
  For pairs numbering 1 through 25, the pair identification colours are outlined below. In cable constructions containing more than 25 pairs, the colours are
repeated as necessary. Colour coded binders are used to identify 25 pair groups of colour coded pairs.
 
Pair Number Tip Colour Ring Colour Pair Number Tip Colour Ring Colour

  Identification of Groups of Pairs
  For cables through 600 pairs, 25 pair groups are identified by their binder colours in the same sequence as the pair identification is accomplished. Group 1
has White-Blue binders. Group 2 has White-Orange binders, etc. In this manner, each pair is uniquely identified. In cables having 25 pairs or less, binders are
normally not used. However, if specified, the binders will be Group 1, White-Blue. For cables of 100 pairs or less, the use of the White binder is optional.
