To convert HEX to HSV, you'll need to go through the following steps. A HEX color code represents a color in the RGB color model, and HSV represents color using Hue, Saturation, and Value. The process involves first converting the HEX to RGB, and then converting the RGB values to HSV.
Steps to Convert HEX to HSV:
Convert HEX to RGB: The HEX color code is a 6-digit string, where the first two digits represent the Red (R), the next two digits represent Green (G), and the last two digits represent Blue (B). Each of these pairs is in hexadecimal format (base 16), so we need to convert them to decimal.
Formula:
ini
R = HEX[0-1], G = HEX[2-3], B = HEX[4-5]
Convert the HEX values to decimal (base 10).
Convert RGB to HSV: After obtaining the RGB values, you can then convert them to HSV using the following formulas.
Max = max(R, G, B)
Min = min(R, G, B)
Delta = Max - Min
Hue (H):
If Delta = 0, then H = 0°.
If Max = R, then H = 60 × ((G - B) / Delta).
If Max = G, then H = 60 × ((B - R) / Delta + 2).
If Max = B, then H = 60 × ((R - G) / Delta + 4).
If H < 0, add 360 to it (to ensure it's in the range of 0° to 360°).
Saturation (S):
If Max = 0, then S = 0 (since there's no color saturation).
Otherwise, S = Delta / Max.
Value (V):
V = Max.
HSV Output:
H (Hue) will be in the range 0° to 360°.
S (Saturation) and V (Value) will be in the range 0 to 1 (or 0 to 100 if you prefer percentages).
Example 1: HEX #FF5733 (a shade of red-orange)
Convert HEX to RGB:
HEX: #FF5733
R = 0xFF = 255, G = 0x57 = 87, B = 0x33 = 51
Convert RGB to HSV:
Max = max(255, 87, 51) = 255
Min = min(255, 87, 51) = 51
Delta = 255 - 51 = 204
Hue (H):
Since Max = R, H = 60 × ((87 - 51) / 204) = 60 × (36 / 204) = 60 × 0.1765 ≈ 10.59°
Saturation (S):
S = 204 / 255 ≈ 0.8 (80%)
Value (V):
V = Max = 255 / 255 = 1.0 (100%)
HSV = (10.59°, 80%, 100%)
Example 2: HEX #33CCFF (a shade of light blue)
Convert HEX to RGB:
HEX: #33CCFF
R = 0x33 = 51, G = 0xCC = 204, B = 0xFF = 255
Convert RGB to HSV:
Max = max(51, 204, 255) = 255
Min = min(51, 204, 255) = 51
Delta = 255 - 51 = 204
Hue (H):
Since Max = B, H = 60 × ((51 - 204) / 204 + 4) = 60 × (-153 / 204 + 4) = 60 × (-0.75 + 4) = 60 × 3.25 = 195°
Saturation (S):
S = 204 / 255 ≈ 0.8 (80%)
Value (V):
V = 255 / 255 = 1.0 (100%)
HSV = (195°, 80%, 100%)
