As an interior decoration expert, I can advise you on how to optimally use PMR visual contrast in your design. This principle consists of creating a strong contrast in colors and brightness between different elements, thus facilitating their identification by visually impaired people. For example, you can opt for stair nosings painted in a dark shade on a light floor, or choose brightly colored door handles on a neutral wall. Switches and sanitary facilities will also benefit from standing out, whether through the use of contrasting materials like brushed metal or frosted glass, or simply by employing opposing shades. You can also play with lighting effects by installing spotlights or LED strips accentuating these strategic areas. By following these principles, you will create an easily identifiable and secure environment, while adding an aesthetic touch to your interior decoration.

To determine the optimal PMR visual contrast level, you need to consider the ambient lighting and the person's vision. Too much contrast can be dazzling, while too little contrast will not be visible enough. Prefer moderate contrast, with at least a 70% difference in brightness between elements.

The most suitable materials for PMR visual contrast are those that exhibit differences in texture and light reflection. For example, combining matte and glossy, or smooth and rough surfaces, creates good visual contrast. Materials like metal, wood, or tile are therefore recommended.

To integrate PMR visual contrast into a coherent interior design, you must ensure that contrasting elements harmonize with the rest of the decoration. Choose colors and materials that match the general style of the room, while ensuring good contrast to facilitate perception for visually impaired people.

The main elements to consider for PMR visual contrast are stair nosings, handles, switches, and sanitary facilities. Ensure that these elements stand out clearly from the rest of the environment, thanks to contrasts in color, brightness, or texture.

To ensure good PMR visual contrast in outdoor spaces, you will need to consider lighting and weather conditions. Use materials and colors that stand out clearly, even in bright sunshine or rainy weather. Also consider signage and ground markings to safely guide visually impaired people.
