HSV Color Model: Hue, Saturation & Value Explained
Screens and software speak in RGB and HEX, but humans rarely think in three channel intensities. HSV (Hue, Saturation, Value) is a cylindrical model that matches how many color pickers, photo tools, and 3D pipelines let you choose and tweak color—rotate the hue, dial vividness, then brighten or darken with value.
For a practical tour of the same three ideas in branding and UI, see our Color Theory 101: Hue, Saturation & Value guide—it pairs well with this technical overview of the HSV model.
What is HSV?
HSV breaks a screen color into three numbers that are easy to reason about:
- Hue (H) — the "which color" angle on a 360° wheel (red near 0°, green near 120°, blue near 240°, and so on).
- Saturation (S) — how intense the hue is, from a neutral gray axis at 0% to full chroma at 100%.
- Value (V) — brightness, often 0–100%. At 0% you get black; with full saturation, 100% value is the brightest display of that hue. When saturation is 0%, value alone sweeps from black to white.
Many apps label the same space HSB (Hue, Saturation, Brightness). HSV and HSB refer to the same family of models; only the naming differs.
HSV vs HSL: same letters, different math
HSL also uses hue and saturation, but it replaces value with lightness. Lightness is defined as the midpoint between the minimum and maximum of RGB channels, which feels natural in CSS hsl() and many design-system palettes. Value in HSV behaves differently near white and black, so hsv(200, 80%, 90%) and hsl(200, 80%, 90%) are not the same color.
Rule of thumb: use HSV when your tool or pipeline exposes it (photo apps, some game engines, classic macOS/Windows pickers). Prefer HSL when you are hand-writing web colors or documenting tokens that mirror CSS.
Why HSV matters in real workflows
- Retouching and grading — adjusting value reads like lifting or crushing exposure while keeping hue stable; saturation isolates chroma without guessing RGB ratios.
- Prototyping UI states — you can nudge value for hover/disabled states, then convert to HEX for production CSS.
- Handoff to print — screens stay in RGB; print uses CMYK. Converting HSV → RGB → CMYK makes the gamut limits explicit (neon HSV picks may not be printable).
Converting HSV to other models
HSV is always translated through RGB under the hood. Useful links on this site:
- HSV to RGB — for APIs, shaders, and apps that expect 0–255 channels
- HSV to HEX — for stylesheets and design handoffs
- HSV to HSL — when jumping between tools
- HSV to CMYK — for layout PDFs and press
- HSV to Pantone — approximate matches for brand libraries

A list of questions we get asked often
Frequently asked questions
Have questions about HSV? We've got you covered.
- What does HSV stand for?
- HSV stands for Hue, Saturation, and Value. Hue is the color angle on a wheel (0–360°), saturation is how vivid the color is, and value is how bright it is (often shown as 0–100%).
- Is HSV the same as HSB?
- Yes. HSB (Hue, Saturation, Brightness) is another name for the same idea as HSV. Different apps use different labels, but the three dimensions work the same way.
- Why do Photoshop and other editors use HSV?
- HSV maps well to how people adjust photos: pick a hue, push saturation for punch, and change value for exposure-like brightness without rebalancing RGB by hand.
- How is HSV different from HSL?
- They share hue and saturation, but value (HSV) and lightness (HSL) are computed differently, so sliders do not behave the same at the extremes. Use HSV when your tool uses it natively; use HSL when writing CSS
hsl()or building design tokens. - Can HSV be converted to RGB, HEX, or CMYK?
- Yes. HSV is converted to RGB first, then to HEX for the web or to CMYK for print (with gamut limits). Our site offers HSV to RGB, HSV to HEX, and HSV to CMYK converters.
