  "text": "Colours used in an ECDIS are defined in an absolute manner, independently from the monitor used (using CIE coordinates). This ensures that ECDIS charts look similar on monitors of different suppliers. CIE values are converted into RGB values by means of colour calibration software which must be used by the manufacturer.\nCommercial displays usual in the trade are seen as matching those requirements.\nDue to the fact that various light conditions might occur on the bridge of a vessel, it is necessary to offer presentations with different brightness levels. For each level a separate colour table exists.\nThe represented colour scheme shall be chosen on the basis of ergonomical and physiological factors and the representation of indications in different colours shall not result in mixed colours by superimposing.",
