About HEX

Hexadecimal codes pack red, green, and blue into six (or eight with alpha) base-16 digits. They are the default in CSS, design tools, and APIs.

About HSV

HSV (also called HSB in some apps) uses hue, saturation (0–100%), and value/brightness (0–100%). It aligns with how many color wheels behave.

How to convert HEX to HSV

Enter a valid HEX value in the calculator. The tool follows the pipeline below: parse your input, hold the color as sRGB (with alpha when relevant), then format the result as HSV.

Accepted shapes include CSS-like functions (e.g. rgb(...), hsl(...)) and compact comma-separated numbers where appropriate. Hex may include or omit the leading #.

Conversion procedure

Parse HEX: optional leading “#” is removed. The parser expects exactly six hexadecimal digits for opaque colors (#RRGGBB), or eight digits when an alpha byte is included (#RRGGBBAA). Each pair is read as base 16 and becomes one channel in the 0–255 range. Invalid length or non-hex characters are rejected.
Resolve to internal sRGB: after parsing, the color is already expressed as three 8-bit channels. If only six hex digits were given, alpha is set to 1. If eight digits were given, the seventh and eighth nibbles define alpha as (alphaByte ÷ 255).
Build HSV: V = max(R,G,B) (as a 0–100% value after scaling), S = 0 if V = 0, else S = (max − min) / max × 100. Hue uses the same 60° family of cases as the HSL step. Output is integer hue and whole percentages: hsv(h, s%, v%).
Finalize: the result string is what you copy from the calculator. The line under the fields summarizes the path in short form (HSV ← sRGB ← HEX). Rounding is intentional so values read like typical CSS; tiny differences versus other apps can still appear because of integer hue, saturation, lightness/value, or ink percentages.
HSL/HSV reminder: when hue, saturation, and lightness/value are shown as whole numbers, more than one underlying RGB can produce the same text. Typing those integers back into a converter may therefore differ by ±1 from a color you first picked as HEX in the Color Picker—that is expected rounding behavior, not a broken formula.

Example

Input (HEX): #3498DB

Output (HSV): hsv(204, 76%, 86%)

Summary

This page converts HEX input into HSV output. The numbered “Conversion procedure” above is the full breakdown: validation and parsing, conversion to a single internal sRGB (+ alpha) sample, derivation of HSV coordinates from that sample, and final rounding to the strings you see in CSS-oriented tools. The same pipeline runs in your browser as you type.

Relationship context

Hexadecimal (#RRGGBB) and HSV (hue, saturation, value) are different ways to describe the same sRGB color (except CMYK, which is an approximate ink model). Converting HEX → HSV does not change the underlying color within the limits of each notation; it only changes how numbers are written.

Example conversions

Sample HEX values and the matching HSV output using the same rules as the calculator.

HEX input	HSV output
#000000	hsv(0, 0%, 0%)
#FFFFFF	hsv(0, 0%, 100%)
#3498DB	hsv(204, 76%, 86%)
