Abstract
The standardization of colours on the official
navigation sea charts worldwide includes
recommendations and technical specifications
to avoid confusion and/or errors due to the
application of different colour combinations
and therefore adversely affect navigation safety.
Since no data on the spectrography of applied
colours have been available so far, spectrographic
measurement is conducted as a starting point for
standardizing the use of colours on sea charts.
This paper presents spectrograms of colours on
the Croatian sea charts, and for the first time,
apart from the visible part of spectrum, it also
shows results for the part of the near-infrared part
of electromagnetic spectrum. In conclusion, the
results of colour use on the Croatian sea charts
are interpreted and a recommendation is made
to measure the spectrography of colours on the
charts of other IHO member states. The results
obtained will be the basis for the introduction
of colour-twins or the system of hidden graphic
elements to expand the information content of
charts, which is the ultimate objective of the
research
Keywords
