RGB to HSV Converter

Converting RGB (Red, Green, Blue) colors to HSV (Hue, Saturation, Value) involves transforming the RGB values into HSV using mathematical formulas. HSV is a color model that defines colors based on their hue, saturation, and value components, while RGB is a color model commonly used in digital displays and design software.

Here are the steps for RGB to HSV conversion:

1. Find the Maximum and Minimum RGB Values: Determine the maximum (Max) and minimum (Min) values among the red (R), green (G), and blue (B) components.

2. Calculate Value (V): Value (V) represents the brightness of the color and is equal to the maximum RGB value divided by 255. V = Max(R, G, B) / 255.

3. Calculate Saturation (S): Saturation (S) represents the intensity of the color and is calculated as follows:

   • If V (Value) is 0 (black), saturation is 0.
   • Otherwise, saturation is calculated as 1 - (Min / Max).

4. Calculate Hue (H): Hue (H) represents the dominant wavelength of the color and is calculated based on the RGB values:

   • If the maximum RGB value is equal to the minimum RGB value, set hue to 0 (undefined).
   • Otherwise, calculate hue using different formulas depending on which RGB component is the maximum:
     • If Max is equal to R, calculate hue as (60 * ((G - B) / (Max - Min)) + 360) % 360.
     • If Max is equal to G, calculate hue as (60 * ((B - R) / (Max - Min)) + 120) % 360.
     • If Max is equal to B, calculate hue as (60 * ((R - G) / (Max - Min)) + 240) % 360.

5. Round Hue Value: Round the calculated hue value to the nearest integer.

Here are some uses of RGB to HSV conversion:

• Digital Design: Designers often need to specify colors in HSV format for digital design work, such as web design, digital graphics, and video editing, to ensure consistency across different digital platforms.
• Color Manipulation: HSV colors provide an intuitive way to manipulate colors based on hue, saturation, and value, making it easier to adjust colors in digital design and photo editing processes.
• Color Analysis: Converting RGB colors to HSV allows for color analysis and visualization, providing insights into the perceptual attributes of colors.

Here are three example inputs and their outputs:

1. Input: RGB values UPDATE toolsfairy_apps.uc_category SET tools_manual = ' WHERE id = 255; 0, 0) for bright red

   • Output: HSV values (0°, 100%, 100%) for pure red

2. Input: RGB values UPDATE toolsfairy_apps.uc_category SET tools_manual = ' WHERE id = 0; 255, 0) for bright green

   • Output: HSV values (120°, 100%, 100%) for pure green

3. Input: RGB values UPDATE toolsfairy_apps.uc_category SET tools_manual = ' WHERE id = 0; 0, 255) for bright blue

   • Output: HSV values (240°, 100%, 100%) for pure blue

Keep in mind that the conversions provided are approximate matches, and the exact HSV values may vary based on factors such as color profiles and color gamuts. It's always recommended to verify the HSV values visually and through digital color samples when accuracy is critical.
