Convert standard RGB color definitions into HSV, the hue, saturation, and value model used by most color pickers and design tools.

Input formats

Provide colors using the standard rgb(r, g, b) syntax with channel values ranging from 0 to 255. Each line is parsed independently in batch mode.

HSV output

The output prints as hsv(h, s%, v%), with hue in degrees from 0 to 360 and saturation and value as percentages. rgb(255, 87, 51) becomes hsv(11, 80%, 100%).

Value vs lightness

Value in HSV is the brightness of the color at full saturation. A pure hue at 100% saturation and 100% value is as vivid as that hue gets, unlike HSL’s lightness, which fades a fully saturated color toward white as lightness rises above 50%.

Batch processing

Paste multiple RGB values, one per line, to convert the full list at once. Use the color picker to preview and adjust the currently selected line.

Frequently Asked Questions

What RGB format does it accept?

CSS rgb() strings like rgb(255, 87, 51), with channels from 0 to 255. Paste one color per line for batch conversion.

What is HSV and how is it different from HSL?

HSV describes a color by hue, saturation, and value, where value is the brightness of the pure hue before white or black is mixed in. HSL uses a lightness channel instead, which reaches its most saturated color at 50% rather than at the top of the scale, so the same hue produces different saturation and lightness numbers in each model.

Is RGB to HSV lossless?

Yes. Both describe the same sRGB color; HSV just re-expresses the three 0-255 channels as a hue angle plus two percentages. Rounding the output to whole numbers can shift the reconstructed RGB value by one unit per channel.

Why does one line show an error?

Each line must be a valid rgb() value with channels in 0-255. Missing commas or parentheses, extra spaces, or out-of-range numbers stop that line from parsing.
