About this conversion

HSV (Hue, Saturation, Value) is the color model behind most visual color pickers. You select a hue on the color wheel, drag horizontally for saturation, and vertically for brightness (value). It is the dominant model in tools like Photoshop, Figma, and many game engines.

However, when you need to use a color in CSS, pass it to an API, or set pixel data in a canvas, you almost always need RGB. This converter takes your HSV values and computes the exact R, G, B integers (0–255) in real time, so you can move freely between a visual color picker workflow and code.

The conversion is lossless within the sRGB gamut. Adjusting the hue slider rotates through the spectrum, saturation controls vibrancy from gray to fully saturated, and value controls brightness from black to the full color. The live preview and copy buttons make it easy to grab exactly the RGB value you need. If you are starting from a photograph or screenshot rather than known HSV values, the Color Picker from Image extracts colors directly from any image.

Frequently Asked Questions

How do I enter HSV values from Photoshop?

In Photoshop's color picker, H is in degrees (0–360), S and B (brightness/value) are percentages (0–100). Enter these same numbers in this tool: H maps to hue, S to saturation, and B to value.

What happens when value is 0 in HSV?

When value (brightness) is 0, the result is always pure black (RGB 0, 0, 0) regardless of the hue or saturation settings. Value controls the overall brightness of the color.

Is the HSV to RGB conversion lossless?

Yes. The conversion is mathematically exact and fully reversible. HSV and RGB describe the same sRGB color space using different coordinate systems.
