HSV to LCh is a free online tool that converts HSV to LCh, helping you quickly convert colors and switch between formats in web design, front-end development, and graphic design. HSV is Describes color through hue (H), saturation (S), and value (V); a format commonly used by color pickers. LCh is The polar form of Lab, describing color with lightness L, chroma C, and hue H. At its core, HSV to LCh takes a color value expressed in HSV and converts it into LCh using a mathematical algorithm. The tool shows the result as both a visual color swatch and a complete CSS string, and you can copy it to the clipboard with a single click—no manual calculation or lookup tables required. This makes color code conversion fast, accurate, and reproducible, and it is suitable for designers, front-end developers, UI engineers, and anyone else who works with color.
What Is HSV to LCh
HSV describes color through hue (H), saturation (S), and value (V). H is 0-360°, and both S and V are 0-100%. It is a common model in color pickers and design software. LCh is the polar form of Lab, describing color with lightness (L), chroma (C), and hue (H). It is more intuitive than Lab and closer to the way HSL is used. First convert HSV to RGB and Lab, and finally turn a and b into the polar C and H.
How to Use HSV to LCh
Using this HSV to LCh tool is very simple and takes just three steps. First, select HSV from the "Source Color Unit" dropdown on the left (it is selected by default), and enter the HSV value you want to convert in the input card. Second, select LCh from the "Target Color Unit" dropdown on the right; the tool instantly calculates and displays the corresponding LCh value, along with a color swatch preview and the complete CSS string, so you can confirm the color and format at a glance. Third, once you are happy with the result, click the "Copy" button to copy the LCh value to your clipboard and paste it straight into your code or design software. If you picked the wrong source or target unit, click the "⇄" button in the middle to swap them with one click. The whole process requires no registration and no data upload—all calculations run locally in your browser.
Use Cases for HSV to LCh
Use this when generating a color scale with the same hue but different chroma. Color picker panels, design software palettes, and interactive situations where a color needs to be adjusted intuitively. Generating color scales in design systems, situations where only the chroma changes while the hue stays fixed, and modern CSS color schemes.
How HSV to LCh Works
First convert HSV to RGB and Lab, and finally turn a and b into the polar C and H. HSV breaks a color down into hue plus vividness plus brightness. Going from black to a bright color increases value V, while going from gray to a pure color increases saturation S. LCh and Lab convert to each other losslessly: L stays the same, C = √(a²+b²), and H = atan2(b, a). This turns the two orthogonal chroma axes into "chroma + hue", which fits how humans think.
Tips for Using HSV to LCh
The reference point for H in LCh differs from that in HSV, so the same visual hue has a different number; recalibrate when migrating across models. The V in HSV is the degree of blackness included; the color is brightest at V=100. Compared with HSL, HSV is better for choosing a color while HSL is better for tuning one. The reference point for H in LCh differs from that in HSL, so the same visual hue has different numbers in LCh and HSL. Migrating directly from HSL to LCh requires recalibrating the hue.
Frequently Asked Questions (FAQ)
Is the H of LCh the same as the H of HSV?
No. The two have different reference points, so the same visual hue has different numbers.
Does HSV to LCh change the color?
No. The conversion only changes the expression.
Is LCh suitable for building color scales?
Yes, especially for generating a scale of the same hue with different chroma.
Are HSV and HSB the same thing?
Yes. HSB is another name for HSV, where B (Brightness) and V (Value) mean the same thing.
Why do color pickers mostly use HSV instead of HSL?
Because the value in HSV is closer to how bright a color actually looks, users perceive the dragging more naturally.
Both LCh and HSL can adjust hue, so what is the difference?
The hue in HSL is perceptually uneven, so the same angular difference looks different under different hues. The hue in LCh is more perceptually uniform and better suited to building color scales.
Which is easier to use, LCh or Lab?
Use Lab for mathematical computation and LCh for manual color adjustment. The two are equivalent; only the coordinate form differs.
Can I convert in the opposite direction?
Yes. You can go directly to the "LCh to HSV" page, or click the "⇄" swap button in the middle of the current page to exchange the source and target units and convert in the opposite direction. The reverse conversion is just as precise, because the color conversion math is reversible.
Can I use the conversion results commercially?
Yes. Color values are numerical information and involve no copyright issues, so you are free to use the conversion results in websites, apps, design work, or commercial projects without authorization or attribution. Do note, however: if the original color comes from material that someone else holds the copyright to, using the color itself is unrestricted, but the copyright to the original material still belongs to its author.
