Conversor de HSV para RGB

HSV stands for Hue, Saturation, and Value. Hue represents the color angle on a 360° wheel (0°=red, 120°=green, 240°=blue). Saturation controls color intensity from 0% (gray) to 100% (pure color). Value controls brightness from 0% (black) to 100% (full brightness). HSV is often preferred by designers because it maps more intuitively to how humans perceive and describe color than RGB does.

The conversion uses the HSV color cylinder model. The hue determines which 60° sector of the color wheel the color falls in, creating six cases. Within each sector, chroma (S×V) and intermediate values are calculated, then mapped to RGB channels. When saturation is zero, the result is a grayscale value where R=G=B=V×255. The math involves conditional logic based on the hue sector, which is why manual calculation is error-prone.

Both HSV and HSL describe color using hue and saturation, but they differ in the third component. HSV uses Value (brightness of the color), while HSL uses Lightness (position between black and white). In HSV, S=100% V=100% gives a pure vivid color. In HSL, S=100% L=50% gives a pure vivid color. HSV is more common in color pickers and graphic design software, while HSL is more common in CSS and web development.

RGB defines colors by mixing light intensities, which is how screens work but not how humans think about color. Asking someone to create 'a slightly darker, less saturated blue' is intuitive in HSV — just reduce V and S. In RGB, achieving the same result requires adjusting all three channels by different amounts. HSV separates the three perceptual dimensions of color (hue, purity, brightness) making it natural for color selection and manipulation tasks.
