HEX8 to LCh is a free online tool that converts HEX8 to LCh, helping you quickly convert colors and switch between formats in web design, front-end development, and graphic design. HEX8 is Adds two transparency digits on top of HEX, in the form #RRGGBBAA. LCh is The polar form of Lab, describing color with lightness L, chroma C, and hue H. At its core, HEX8 to LCh takes a color value expressed in HEX8 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 HEX8 to LCh
HEX8 is a hexadecimal color with transparency, in the form #RRGGBBAA for a total of 8 digits. The first 6 digits are the same as a regular HEX, and the last 2 represent the Alpha transparency. 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. Take the first 6 digits, convert to RGB and Lab, and finally turn a and b into the polar C and H, discarding Alpha.
How to Use HEX8 to LCh
Using this HEX8 to LCh tool is very simple and takes just three steps. First, select HEX8 from the "Source Color Unit" dropdown on the left (it is selected by default), and enter the HEX8 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 HEX8 to LCh
Use this when generating a color scale with the same hue but different chroma. Modern CSS, gradients that need transparency, and design systems that express brand colors with transparency. Generating color scales in design systems, situations where only the chroma changes while the hue stays fixed, and modern CSS color schemes.
How HEX8 to LCh Works
Take the first 6 digits, convert to RGB and Lab, and finally turn a and b into the polar C and H, discarding Alpha. HEX8 is essentially the hexadecimal form of RGBA: the three RGB channels and the Alpha channel are each converted to two hexadecimal digits, for example rgba(255,87,51,0.5) corresponds to #FF573380. 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 HEX8 to LCh
Alpha is discarded. The reference point for H in LCh differs from that in HSL, so recalibrate when migrating across models. HEX8 is more compact than RGBA and works well in CSS variables, but it is less readable than RGBA, so teams should add comments when collaborating. 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)
Does HEX8 to LCh keep the transparency?
No. LCh contains no transparency.
Is the H of LCh the same as the H of HSL?
No. The two have different reference points.
Is LCh suitable for building color scales?
Yes, especially for generating a scale of the same hue with different chroma.
How is the transparency of HEX8 calculated?
The last two digits are the hexadecimal value of Alpha: FF means fully opaque, 80 means about 50%, and 00 means fully transparent.
Do all browsers support HEX8?
All major modern browsers support it, including Chrome, Firefox, Safari, and Edge. IE does not.
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 HEX8" 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.
