RGB to HSV Color Conversion Tool

RGB to HSV color conversion

RGB to HSV conversion helps you transform Red, Green, and Blue color values into Hue, Saturation, and Value. The process includes normalizing the RGB values (0–1), finding the maximum and minimum channels, and calculating Hue based on dominant color, Saturation by color intensity, and Value from the brightest channel. This method is widely used in color pickers and image editing because HSV is more intuitive for understanding colors.

How to Convert RGB to HSV

RGB to HSV color conversion formula

The conversion from RGB to HSV requires normalization, identifying color ranges, and applying mathematical formulas for each component.

The process of converting RGB to HSV involves four main calculations:

1. RGB values

2. Find C_max and C_min and Delta

3. Calculate Hue (H)

4. Calculate Saturation (S)

5. Calculate Value (V)

What is RGB to HSV Conversion

RGB (Red, Green, Blue) is commonly used for digital screens.
HSV (Hue, Saturation, Value) represents colors in a way that matches human perception.

To convert RGB to HSV, we transform RGB components into Hue (color angle), Saturation (color intensity), and Value (brightness).

HSV is widely used in:

• Graphic design

• Photo editing

• UI/UX color systems

• Color pickers

• Digital painting tools

1. RGB Values

Convert R, G, B from the 0–255 range to the 0–1 range.

R' = R / 255
G' = G / 255
B' = B / 255

2. Find Cmax & Cmin and Delta

Value simply equals the maximum normalized component.

V = Cmax

V ranges from 0 to 1 (or 0% to 100%).

5. Value Calculation (V):

Cmax = max(R', G', B')
Cmin = min(R', G', B')
Δ = Cmax – Cmin

4. Saturation Calculation (S):

If Cmax = 0 → S = 0
Else → S = Δ / Cmax

Saturation ranges from 0 to 1 (or 0% to 100%).

3. Hue Calculation (H):

Hue represents the color angle on a color wheel (0° to 360°).

If Δ = 0 → H = 0
Else if Cmax = R' → H = 60 × [((G' − B') / Δ) mod 6]
Else if Cmax = G' → H = 60 × [((B' − R') / Δ) + 2]
Else if Cmax = B' → H = 60 × [((R' − G') / Δ) + 4]

Hue ranges from 0° to 360°.
