Abstract: Color analysis using colorimetric detection has shown significant advancements, although it still faces challenges when capturing color images under varying illumination conditions. This study explores the utilization of the HSV (hue, saturation, value) color model for precise color analysis, enabling the differentiation of colors based on their type, intensity, and brightness without being affected by illumination. The HSV model, measured by the Euclidean Distance (ΔE) value, is employed to investigate the impact of fluoride solution pH and concentration on the colorimetric detection process of fluoride ions using a thiourea receptor. The colorimetric detection of fluoride ions at low and high pH levels decreases ΔE values and notable color changes. Additionally, the HSV model elucidates the color variations induced by fluoride concentration and demonstrates a linear relationship up to 0.9809.
