We designed a comprehensive grid-based color mixing framework using four strategically selected primary fibers (Grey, Cyan, Magenta, and Yellow), from which 66 distinct yarn samples were produced and characterized. Two specialized BPNN architectures were developed: one predicting blend ratios from spectral reflectance data, and another forecasting resultant CIELAB values from known blend ratios. The models were trained, validated, and tested using industry-standard metrics, achieving high accuracy with mean squared error values consistently below 0.03 for ratio prediction and color differences (ΔE) generally around 2.0 for color prediction. Practical validation involved producing yarns based on BPNN-predicted recipes, which demonstrated close visual and spectrophotometric agreement with target colors. Beyond addressing the limitations of conventional color theories, this bidirectional prediction framework offers significant practical implications for textile manufacturing, enabling both precise recipe formulation from target colors and accurate color forecasting from known recipes.

However, despite its potential, key challenges remain: the incomplete characterization of plant extracts hampers reproducibility, control over NP morphology, and large-scale implementation. While many studies report successful NP synthesis, a precise understanding of the specialized metabolites involved is still lacking. Bridging this knowledge gap is crucial for optimizing NP properties and expanding their biomedical, catalytic, and industrial applications. This review critically examines the role of specialized plant metabolites in NP synthesis, detailing analytical techniques, such as LC-MS, FTIR, and NMR, for their characterization. Scalability remains a key challenge in plant-mediated nanoparticle synthesis, with reproducibility often limited by non-standardized extraction methods. Strategies such as protocol harmonization, the integration of advanced analytical tools, and the application of artificial intelligence (AI) can significantly enhance consistency and predictability.
