Abstract
The visibility at low luminance levels is a very discussed topic which is solved across the whole
industry. The warning elements that increase the visibility of people or things are very necessary and
desirable at low luminance levels caused by an unexpected situation (for example accidents, power
failure, natural disaster). Contrary to these experimental works that are focused on adaptive luminance
of color lights, the proposed work is focused on the perception of the color surface contrast on the
mesopic and photopic of luminance level, where differences from Purkinje shift and the
pseudotritanopic defect have occurred. Selected steel plates were measured with a
spectrophotometer to determine their color coordinates in the CIELAB color space. Various
luminescence plates were included in the visual assessments. A suitable combination of colors with
the high color purity, the black and white contrast strip and the phosphorescent pigments appear as
the potentially beneficial solution that will increase visibility.
