Color intelligence

At OliKrom company, we have deliberately combined the words "intelligence" and "color" to define our unique expertise: the art of making colors speak to track, inform, amplify, camouflage,...

This know-how allows us to control color and program the material to develop custom-made smart technology (paint & ink) with a large choice of changing colors (blue, red, green, black, orange, pink, purple, yellow...).

We then ensure the industrial production of smart materials from the specialty pigments to the reactive inks and paints.

Visual detection by the human eye

Colors are a part of our language and culture. Each color has a wavelength, and each color affects our attention in a different ways based on the detection in the range of blue, red, green, black, orange, pink, purple, yellow...

Nevertheless, the ability of a human being to distinguish a color or a luminosity varies according to his age and the light intensity emitted by his immediate environment.

For our teams, working on colors implies modulating the optical response of materials according to the predominant process: scotopic vision (based on night view), mesopic vision (twilight view), photopic vision (day view) or glare effect.

We adjust the photochemical cascade of the pigment(s), the quantum yield, the excitation and emission wavelengths, the shape of each potential well, the luminescence processes involved (fluorescence/phosphorescence), the time dependency.

Signal processing can be used to detect a color switching for industrial safety purposes. In this context, our teams calibrate the optical modulation of the material to respond to the desired energy source: temperature, pressure, etc. Signal processing is carried out at the molecular level to control the switching properties: reversibility (or irreversibility), memory effect, energy threshold, choice of colors, etc.

Other needs based on color intelligence concern the perception of an object or a product according to the brightness of its environment. The stakes (and the uses) are multiple: to reinforce visibility at night (road safety, sea rescue...), or to modify the perception during the day to enhance a color for aestheticism, luxury, cosmetics, watchmaking...

To provide information and create this optical material-machine interaction, our scientific engineers program the optical response of the material. This involves real information processing on a molecular scale to select the right effect, the right absorption and/or emission wavelength, the sensitivity of the detection thresholds, the triggering speed, not forgetting all the business constraints inherent to the targeted sector of activity.

This is a rapidly expanding field of application. Our researchers on intelligence color are involved in many innovative projects associated with Industry 4.0, predictive maintenance, production process automation, future mobility...

For example, OliKrom has been selected by GRTgaz to develop a breakthrough technology in the field of gas leak monitoring by drone.

The possibilities in this scientific sector are numerous. They have the common goal of creating an interaction with the animal kingdom, where each species has its own particularities: vision of colors, contrasts, intensity.

The cat, for example, has excellent vision that allows it to perceive ultraviolet light. Other species are short-sighted but sensitive to light.

This is a challenge that our research and development teams have taken up. This requires us to customize the chemical composition of intelligent materials to modulate the optical response according to the stimulus and the target species.

As a committed company, our actions are voluntarily dedicated to improving animal welfare and protecting animals. For example, our Research Department is currently working to develop a virtual barrier to prevent wild boar and deer from crossing a road.
