This document specifies 10 additional test colours to test the colour reproduction of Grade 1 professional video monitors. The colours have clearly distinguishable names, such as: Luminous Bright Orange' and 'Reddish Purple'.
The colours defined in this document extend the list of colours specified in EBU Tech 3325 v1.0 "Methods for the measurement of the performance of studio monitors". They should be implemented as narrow-range, 10-bit signals. Note that EBU Tech 3325 v2.0 no longer uses this supplement; as it has incorporated the new colours directly.
Version 1.1 of this supplement corrects the Y value for the colour Anchusa (should be 0.0422).
