Python Math: Exercise-77 with Solution

Write a Python program to convert RGB color to HSV color.

Note: RGB - RGB (Red, Green, Blue) describes what kind of light needs to be emitted to produce a given color. Light is added together to create form from darkness. RGB stores individual values for red, green and blue. RGB is not a color space, it is a color model. There are many different RGB color spaces derived from this color model, some of which appear below.

HSV - (hue, saturation, value), also known as HSB (hue, saturation, brightness), is often used by artists because it is often more natural to think about a color in terms of hue and saturation than in terms of additive or subtractive color components. HSV is a transformation of an RGB colorspace, and its components and colorimetry are relative to the RGB colorspace from which it was derived.

Sample Solution:

Python Code:

def rgb_to_hsv(r, g, b): r, g, b = r/255.0, g/255.0, b/255.0 mx = max(r, g, b) mn = min(r, g, b) df = mx-mn if mx == mn: h = 0 elif mx == r: h = (60 * ((g-b)/df) + 360) % 360 elif mx == g: h = (60 * ((b-r)/df) + 120) % 360 elif mx == b: h = (60 * ((r-g)/df) + 240) % 360 if mx == 0: s = 0 else: s = (df/mx)*100 v = mx*100 return h, s, v print(rgb_to_hsv(255, 255, 255)) print(rgb_to_hsv(0, 215, 0))

Sample Output:

(0, 0.0, 100.0) (120.0, 100.0, 84.31372549019608)
