A Methodology for Matching Colors in Product Design Using Gradient Colors and a New Aesthetic Measurement Method

ABSTRACT In recent years, gradient color products have gained popularity for their vibrant and eye‐catching appeal, becoming a key visual trend across various design fields such as packaging, fashion, and furniture. Spearheaded by Pantone, these color schemes must harmonize with evolving public aesthetics and product design trends. Gradient‐color products, compared to single‐color ones, attract more consumer attention. However, designing effective gradient color schemes presents challenges, as they must quickly align with public preferences. This study proposes a gradient‐color matching method tailored to these preferences, supported by an innovative aesthetic measurement formula. RGB and Pantone models, integrated with the Munsell color system, were used to create gradient color strips through arithmetic progression. Eye‐tracking experiments identified visual hotspots in these strips, which informed the calculation of aesthetic values. Representative color points served as initial points for performing tricolor aesthetic measurements, thereby eliminating color schemes with insufficient aesthetic values. Running shoes served as design cases to apply and test the method. Public perception was evaluated through an aesthetic questionnaire, and Pearson correlation validated the results, showing a strong alignment with public aesthetics. The proposed method can assist future designers in developing gradient color recommendations for various products.
