Convert unlimited colours with no signup, no subscription, and no usage caps. The HSV/HSB color converter is completely free forever with no ads blocking the interface.
Common Use Cases for HSV/HSB Color Converter
Graphic & UI Design
Designers use the HSV/HSB color converter to match colours from design tools like Photoshop, Illustrator, and Figma - which all use HSV/HSB in their colour pickers - to HEX and RGB for web implementation.
Design Tool Compatibility
Figma, Sketch, Adobe XD, and most design applications use HSV as their default colour model. The HSV/HSB color converter makes it easy to translate these colour values to CSS-compatible formats.
Image & Photo Editing
Photo editors use the HSV/HSB color converter when working with image adjustment tools - hue/saturation/brightness sliders in photo editing software correspond directly to the HSV colour model.
Colour Theory & Education
Students and educators use the HSV/HSB color converter to understand how hue, saturation, and brightness interact. The visual picker makes it easy to see how changing one channel affects the colour.
Mobile App Development
Mobile developers use the HSV/HSB color converter when implementing colour pickers or image filters that use the HSV/HSB colour space, which is common in iOS (UIColor) and image processing libraries.
Colour Manipulation Algorithms
Developers building colour manipulation features - like dynamic themes, colour filters, or image processing - use the HSV/HSB color converter to understand how HSV values map to RGB for their algorithms.
Understanding HSV / HSB Color Space
What is HSV / HSB Color Space?
HSV (Hue, Saturation, Value) - also known as HSB (Hue, Saturation, Brightness) - is a colour model that describes colours in terms of human perception rather than device primaries. Unlike RGB which mixes red, green, and blue light, HSV separates colour into three intuitive components: Hue (the colour type, 0-360°), Saturation (the intensity/purity, 0-100%), and Value/Brightness (the lightness/darkness, 0-100%). Our HSV/HSB color converter makes it easy to translate between HSV and other colour formats used in web development.
How Our HSV/HSB Color Converter Works
- Adjust HSV values visually or numerically: Use the interactive saturation/brightness square to click or drag to any colour. Use the hue bar to select the base colour. Or enter precise H, S, V values directly using the sliders or number inputs. All three methods update each other in real time.
- All format equivalents update instantly: As you adjust any HSV value, the equivalent HEX, RGB, HSL, and individual channel values all update in real time. The colour preview swatch shows exactly what the selected colour looks like.
- Copy any value or all values:Click the Copy button next to any output row to copy that specific format, or use “Copy All Values” to copy HSV, HEX, RGB, and HSL together.
HSV vs HSL - What's the Difference?
- Hue (H): Identical in both HSV and HSL. Represents the colour angle on the colour wheel, from 0° (red) through 360° (back to red).
- Saturation (S): Similar in both models but with a key difference. In HSV, saturation measures the purity relative to the brightness. At 100% saturation and 100% brightness, the colour is fully pure. In HSL, saturation behaves differently because it accounts for lightness.
- Value/Brightness (V) vs Lightness (L): This is the main difference. HSV Value ranges from 0% (black) to 100% (full colour). HSL Lightness ranges from 0% (black) through 50% (pure colour) to 100% (white). This makes HSL symmetric (adds white at the top) while HSV is cone-shaped (adds only black at the bottom).
- Why both exist: HSV/HSB is used in most design applications (Photoshop, Figma) because it is more intuitive for colour selection. HSL is used in CSS because it makes creating tints and shades more predictable.
HSV/HSB in Design and Development
HSV/HSB is the standard colour model in virtually all design and photo editing software - Adobe Photoshop, Adobe Illustrator, Figma, Sketch, GIMP, Affinity, and most mobile photo editing apps all use HSV/HSB in their colour pickers. This is because HSV corresponds directly to how humans perceive and describe colour: we think of colours first by their hue (red, blue, green), then by how saturated (vivid vs muted) and how bright (light vs dark) they are.
In web development, HSV is essential for image processing (Canvas API filters and pixel manipulation), colour picking UI components, and any algorithm that needs to manipulate colour in a perceptually meaningful way. Our HSV/HSB color converter bridges the gap between design tool colours and web implementation formats.

Frequently Asked Questions About HSV/HSB Color Converter
HSV stands for Hue, Saturation, Value (also called HSB for Hue, Saturation, Brightness). It represents colours using three components: Hue (the colour type, 0-360° on the colour wheel), Saturation (the intensity or purity, 0-100%), and Value/Brightness (the lightness, 0-100%). HSV is the standard colour model used in most design applications like Photoshop and Figma.
You can use the interactive colour picker by clicking or dragging on the saturation/brightness square and the hue bar to visually select any colour. You can also enter precise HSV values using the sliders or number inputs for H (0-360), S (0-100%), and V (0-100%). All equivalent formats update in real time as you adjust.
HSV (Value) and HSL (Lightness) differ in the third channel. In HSV, V ranges from 0% (black) to 100% (fully saturated colour). In HSL, L ranges from 0% (black) through 50% (pure colour) to 100% (white). This means HSV is better for colour selection (used by design tools), while HSL is better for creating tints and shades programmatically in CSS.
Yes. All conversion happens 100% client-side in your browser using JavaScript and the Canvas API. Your colour values are never sent to any server, never stored, and never transmitted anywhere. The HSV/HSB color converter is completely private.
HSV/HSB is used in design applications because it matches how humans intuitively describe and select colours. We think of colours first by hue (is it red, blue, or green?), then by saturation (is it vivid or muted?), and then by brightness (is it light or dark?). This makes HSV/HSB the most intuitive colour model for manual colour selection.
Yes. The HSV/HSB color converter is 100% free with no signup required, no premium features, and no usage limits. Convert unlimited colours without any restrictions or hidden costs.
Hue (H) ranges from 0 to 360 degrees, where 0° = red, 60° = yellow, 120° = green, 180° = cyan, 240° = blue, 300° = magenta, and 360° = back to red. Saturation (S) ranges from 0% (greyscale) to 100% (fully pure colour). Value/Brightness (V) ranges from 0% (black) to 100% (maximum brightness).
Yes - the HSV/HSB color converter is bidirectional. Adjust any of the HSV sliders to see the RGB/HEX equivalents, or you can click on the colour preview to see the current RGB values. The tool provides all equivalent formats - HEX, RGB, HSL, and HSV - in one view.
