How HSV to RGB Conversion Works
Step 1: Normalize Input Values
First, we need to normalize our HSV values to the ranges used in the algorithm:
- Hue (180°): 0.5 (divided by 360)
- Saturation (100%): 1.0 (divided by 100)
- Value (100%): 1.0 (divided by 100)
Step 2: Calculate Intermediate Values
Next, we calculate several intermediate values:
i = floor(H × 6) = floor(0.5 × 6) = 3
f = H × 6 - i = 0.5 × 6 - 3 = 0
p = V × (1 - S) = 1.0 × (1 - 1.0) = 0
q = V × (1 - f × S) = 1.0 × (1 - 0 × 1.0) = 1
t = V × (1 - (1 - f) × S) = 1.0 × (1 - (1 - 0) × 1.0) = 0
Step 3: Determine RGB Based on Hue Sector
The RGB values are determined based on which sector the hue falls in:
For hue in sector 3, we set (R,G,B) = (p,q,V)
This results in:
- R = 0
- G = 1
- B = 1
Step 4: Scale to 8-bit RGB Values
Finally, we scale our normalized RGB values (0-1) to the standard 8-bit range (0-255):
- R = round(0 × 255) = 0
- G = round(1 × 255) = 255
- B = round(1 × 255) = 255
Final RGB: (0, 255, 255)
Hexadecimal: #00FFFF
Understanding Color Models
HSV Color Model
HSV (Hue, Saturation, Value) is a cylindrical color model that represents colors in terms of:
- Hue (H): The color type, represented as an angle around the color wheel (0-360°)
- Saturation (S): The intensity or purity of the color (0-100%)
- Value (V): The brightness of the color (0-100%)
HSV is often preferred by designers and digital artists as it's more intuitive for color selection and manipulation than RGB.
RGB Color Model
RGB (Red, Green, Blue) is an additive color model where colors are created by mixing red, green, and blue light:
- Red (R): The amount of red light (0-255)
- Green (G): The amount of green light (0-255)
- Blue (B): The amount of blue light (0-255)
RGB is the standard color model used in digital displays, web design, and computer graphics.

| Color | Hue (°) | Saturation (%) | Value (%) | RGB | Hex |
|---|---|---|---|---|---|
| Red | 0 | 100 | 100 | (255, 0, 0) | #FF0000 |
| Yellow | 60 | 100 | 100 | (255, 255, 0) | #FFFF00 |
| Green | 120 | 100 | 100 | (0, 255, 0) | #00FF00 |
| Cyan | 180 | 100 | 100 | (0, 255, 255) | #00FFFF |
| Blue | 240 | 100 | 100 | (0, 0, 255) | #0000FF |
| Magenta | 300 | 100 | 100 | (255, 0, 255) | #FF00FF |
| Black | 0 | 0 | 0 | (0, 0, 0) | #000000 |
| White | 0 | 0 | 100 | (255, 255, 255) | #FFFFFF |
How to Use HSV to RGB Color Conversion
Basic Usage
- Adjust the Hue slider to select the base color (0-360°)
- Set the Saturation slider to determine the color intensity (0-100%)
- Use the Value slider to control the brightness (0-100%)
- Alternatively, click directly on the color wheel to set hue and saturation at once
- Use the vertical slider beside the wheel to adjust the brightness value
- View the converted RGB values in various formats (decimal, hex, normalized)
- Click the copy icon next to any format to copy it to your clipboard
