In 2018, OliKrom developed LuminoKrom, the first photoluminescent road marking paints to provide self-sustaining and long-lasting luminous signage at night.

LuminoKrom glow-in-the-dark marking presents 3 major benefits for the city of the future:

• Improving night-time urban safety by providing luminous guidance and warnings for users on cycle and pedestrian infrastructure.
• Enhancing safety in public and private buildings by improving the visibility of emergency exits and escape routes in dimly lit environments or during power cuts.
• Offering great creative possibilities for architectural, interior design and urban art projects.

Presenting the highest levels of luminance ever achieved, LuminoKrom technology operates without electricity, wiring or special maintenance, making it a sustainable and cost-effective solution.

Already adopted in many countries by municipalities, local authorities and private organizations, this innovative marking directly addresses the challenges of urban mobilities safety, energy efficiency, and ecological transition.

Its unique luminous signature combines functionality with aesthetics, inspiring designers and city planners worldwide.

Year after year, LuminoKrom has expanded its product offer, to meet the specific needs of local authorities and urban designers. It offers now a complete range of outdoors or indoors glow-in-the-dark paintings, sprays and adhesive tapes in several colors, all with very high luminance levels. At OliKrom, we are committed to developing intelligent materials that contribute to safer, more sustainable, and more inclusive environments. LuminoKrom is one of our innovations thought to support the global shift towards energy sobriety and environmentally responsible solutions.

LuminoKrom® is the only photoluminescent paint in the world to deliver up to 10 hours of luminescence outdoor (15h indoor), while most luminescent products on the market provide an afterglow of only 2.5 hours. This unique performance makes LuminoKrom® a breakthrough solution for safety and sustainable mobility. In 2026, LuminoKrom® launches the first high luminance outdoor adhesive tape! It completes a wide range of outdoor and indoor glow-in-the dark solutions with several colors and packaging.

Since 2021, OliKrom belongs to the “Coq Vert” Green-Tech Community, launched by Bpifrance with ADEME and the French Ministry of Ecological Transition.

Our mission is to work on smart coatings designed to interact with their environment, creating eco-innovative opportunities to address today’s environmental challenges. LuminoKrom environmental impacts have been assessed by APESA using Life Cycle Analyses (following ISO 14040 and 14044 standards) showing -90% impact vs solar stud lightings.
