HSV to Hex Converter
Convert HSV hue, saturation, and value (brightness) numbers from any color picker into a 6-digit hex code ready for CSS and design tools.
How HSV to Hex Conversion Works
HSV (hue, saturation, value) first converts to RGB using a piecewise formula based on which 60° segment of the color wheel the hue falls into, scaled by saturation and value. Once the red, green, and blue channels are known (0-255 each), each converts to a 2-digit hex pair and the three pairs concatenate into a standard 6-digit hex code.
HSV to Hex Example, Step by Step
hsv(0, 100%, 100%) = #FF0000
hsv(0, 100%, 100%) = #FF0000
Hue = 0 (falls in the 0-60 segment) Saturation = 100%, Value = 100% Chroma = V x S = 1.0 X = 0 (since hue = 0) m = V - C = 0 RGB (0-1) = (1.0, 0, 0) Scale to 0-255: R=255, G=0, B=0 255 (decimal) = FF (hex) -> Red 0 (decimal) = 00 (hex) -> Green/Blue
| Step | Description | Result |
|---|---|---|
| Find the hue segment | hue 0 falls in the 0-60° segment | red-dominant |
| Compute chroma | V x S = 1.0 | C = 1.0 |
| Derive RGB (0-1 range) | based on chroma and hue position | R=1.0, G=0, B=0 |
| Scale to hex | 255 (decimal) = FF (hex) | #FF0000 |
This example round-trips exactly with no rounding drift, since 0°, 100%, and 100% all map to clean RGB values with no fractional remainder.
Common Mistakes With HSV to Hex
- Entering saturation or value as a raw decimal (0.92) instead of a percentage (92).
- Confusing HSV's value with HSL's lightness — plugging HSL numbers into an HSV converter gives the wrong color.
- Assuming a rounded HSV reading always round-trips to the exact original hex — small rounding drift is possible.
Frequently Asked Questions
How do you convert HSV to hex?
First convert hue, saturation, and value into RGB channels using the standard HSV-to-RGB formula, then convert each RGB channel (0-255) to a 2-digit hex pair, same as any RGB-to-hex conversion.
What format does this tool accept for HSV input?
Either plain comma-separated numbers (221, 84%, 92%) or a full hsv() function string (hsv(221, 84%, 92%)) — both work the same.
What's the hex value of hsv(0, 100%, 100%)?
#FF0000 (pure red) — 0° hue with full saturation and full value sits at the reddest, brightest point of the color wheel.
Can I paste values straight from a color picker's HSV sliders?
Yes — this tool accepts the same hue (0-360), saturation (0-100%), and value (0-100%) ranges shown in most color picker UIs, so you can copy them directly.
Is HSV to hex the same conversion as HSB to hex?
Yes — HSV and HSB are the same color model under different names, so converting either to hex uses identical math and produces identical results for the same numbers.
