The American Association of Textile Chemists and Colorists (AATCC) is an industry advocacy group focusing on the effective application of color and functional finishes on textiles.  Textiles are used in many sectors including transportation, military/government, industrial, medical/ healthcare, sports/fitness, and fashion, thus the business and end-use requirements vary widely. As we see rapid changes in global business, AATCC “continues to evolve to meet the needs of those in  the ever-changing textile, apparel, and materials industries.” [1] The textile, apparel, and materials industries are huge. The global apparel retail market drives about US$1.8 trillion in revenue. [2] Textile mills and apparel…

Color Inspiration at a Design-Driven Brand According to Yun Chen, choosing colors is like exploring a “lonely, uncharted wilderness.” [5] It is up to a designer’s talent and vision to select a collection of colors to represent the aesthetic of a design concept. Some designers see new colors clearly in their mind’s eye and need a way to document them. Others go exploring in stores, galleries. This textile series will share technical insights and wisdom of AATCC members. The "Second C" series will focus on color. If you wish to contribute your own technical insights on topics of interest to AATCC…

Abstract A colour rendition chart, named Preferred Memory Colour Chart (PMCC), has been produced. It includes 30 colours, diving into three groups: preferred memory colours, reference colour gamut and a grey sale. The methods to derive these colours and the colour specification of each colour were covered. Its applications were also introduced. 1.Introduction XRite ColorChecker chart (XCCC) [1], which has been widely used in imaging industry for five decades, as a colour reproduction target. It has been widely used to build colour correction metric for cameras under different illuminants, to check the fidelity against the image on displays. The chart…

Why Do Cameras “See Colors Wrong”? Have you ever noticed that two cameras capture the same scene with noticeably different colors? One of the main reasons lies in the light source used during production and testing. A camera’s “eyes” — its image sensors — are highly sensitive to light. If the spectral power distribution (SPD) of the test light source is unstable, the camera may misinterpret colors or brightness. That’s why controllable, spectrally stable light sources are essential in both camera production lines and laboratories. Among these, multi-channel spectrally tunable LED light sources are increasingly adopted by manufacturers and research…

Light. Protection. Challenges. Light is the medium through which art is brought to life, but improper illumination can also become a potential threat to cultural heritage. Research indicates that organic pigments—particularly red and yellow—are highly susceptible to fading or degradation when exposed to inappropriate lighting conditions, with significant damage occurring in just a few months. To combat this, leading museums around the world are increasingly adopting spectrally tunable LED lighting technology. Not only does this technology offer outstanding energy efficiency, but it also represents a breakthrough in precise spectral control: effectively filtering out harmful UV/IR radiation, regulating blue light levels,…

In the World of Color, Precision Matters More Than You Think! From smartphones and automobiles to architecture, home appliances, and medical equipment, color, material, and finish (CMF) design plays a crucial role in shaping our visual experiences. In industrial manufacturing, ensuring color consistency and stability is essential, as it directly impacts brand identity, product quality, and consumer purchasing decisions. But did you know? The same color can appear drastically different under different lighting conditions! This is why color standardization and precise control are critical in industrial design, brand marketing, and manufacturing processes. This necessity is at the heart of both…

Unlike traditional color communication methods, LEDSimulator offers a real-time, error-free total appearance color management system. It enables instant reproduction of colors, textures, and translucency, ensuring consistency, speed, and accuracy in color communication across the global supply chain between designers, brands, and manufacturers. This not only reduces communication costs significantly but also shortens the time-to-market for products. Through the LEDSimulator viewing window, designers, brand managers, and manufacturers can bypass time-consuming sample production and shipping. They can easily specify and verify fabrics’ color and texture in their full appearance, providing a seamless and efficient communication platform for color and texture matching. Since its…
