Algorithm Research on Automatically Generating N Visually Distinct Colors Based on HSL Color Model
This paper provides an in-depth exploration of algorithms for automatically generating N visually distinct colors in scenarios such as data visualization and graphical interface design. Addressing the limitation of insufficient distinctiveness in traditional RGB linear interpolation methods when the number of colors is large, the study focuses on solutions based on the HSL (Hue, Saturation, Lightness) color model. By uniformly distributing hues across the 360-degree spectrum and introducing random adjustments to saturation and lightness, this method can generate a large number of colors with significant visual differences. The article provides a detailed analysis of the algorithm principles, complete Java implementation code, and comparisons with other methods, offering practical technical references for developers.
