Direct answer

Convert HSV used for color pickers, hue rotation and graphics controls into a CSS named-color lookup or the nearest built-in CSS name, ready for readable CSS keywords and human-friendly swatch labels. Channel normalization and integer/percentage formatting can make a HSV → COLORTONE → HSV round trip differ from the starting value.

What this tool does

Convert HSV used for color pickers, hue rotation and graphics controls into a CSS named-color lookup or the nearest built-in CSS name, ready for readable CSS keywords and human-friendly swatch labels. Use this focused route when your source is already HSV and the next system specifically expects CSS Color Name (Colortone); use the general converter when you need several representations at once.

Verified capabilities

Valid HSV input

Enter hue in degrees plus saturation and value as percentages. Hue is normalized around the color wheel.

Read the COLORTONE result

a CSS named-color lookup or the nearest built-in CSS name

Check the accuracy boundary

Channel normalization and integer/percentage formatting can make a HSV → COLORTONE → HSV round trip differ from the starting value. Compare the result with the intended destination before reusing it.

When to use it

  • Use this focused route when your source is already HSV and the next system specifically expects CSS Color Name (Colortone); use the general converter when you need several representations at once.
  • Convert HSV used for color pickers, hue rotation and graphics controls into a CSS named-color lookup or the nearest built-in CSS name, ready for readable CSS keywords and human-friendly swatch labels.
  • HSV → COLORTONE: readable CSS keywords and human-friendly swatch labels.

How to use the tool

  1. Enter the source color

    Enter hue in degrees plus saturation and value as percentages. Hue is normalized around the color wheel. In “How to use the tool: Enter the source color”, apply this specifically to HSV to CSS Color Name (Colortone) Converter.

  2. Review the normalized preview

    Use the sliders, direct field, preset swatches or system picker when available. The preview exposes normalization before COLORTONE formatting.

  3. Copy the target value

    Copy the COLORTONE row. Alternate rows stay visible for comparison, but this page's intent remains HSV → COLORTONE.

  4. Check the accuracy boundary

    Channel normalization and integer/percentage formatting can make a HSV → COLORTONE → HSV round trip differ from the starting value. Compare the result with the intended destination before reusing it. Use the preview to catch a parsing mistake before copying the COLORTONE row.

Controls explained

Valid HSV input

Enter hue in degrees plus saturation and value as percentages. Hue is normalized around the color wheel. In “Controls explained: Valid HSV input”, apply this specifically to HSV to CSS Color Name (Colortone) Converter.

Read the COLORTONE result

a CSS named-color lookup or the nearest built-in CSS name. Colortone is AppKiro's label for CSS color-name lookup, not a standard color space. Forward matching uses Euclidean RGB distance.

How the result is produced

Enter hue in degrees plus saturation and value as percentages. Hue is normalized around the color wheel. The workbench parses the source to an sRGB triple, then formats a CSS named-color lookup or the nearest built-in CSS name. HSV value is the largest RGB channel, not perceived lightness, and HSV is not a standalone CSS syntax. Colortone is AppKiro's label for CSS color-name lookup, not a standard color space. Forward matching uses Euclidean RGB distance.

Accuracy and limitations

  • Channel normalization and integer/percentage formatting can make a HSV → COLORTONE → HSV round trip differ from the starting value.
  • HSV value is the largest RGB channel, not perceived lightness, and HSV is not a standalone CSS syntax.
  • Colortone is AppKiro's label for CSS color-name lookup, not a standard color space. Forward matching uses Euclidean RGB distance.

Processing and privacy

Values are converted in the page with local TypeScript functions. No color value needs to be uploaded for this calculation.

Practical tips

  • Keep a copy of the original HSV value when comparing rounded COLORTONE output.
  • Use the preview to catch a parsing mistake before copying the COLORTONE row.
