Tool usage guide
The sRGB to LCH Converter allows you to accurately transform sRGB color values into the perceptually uniform LCH color space, ensuring consistent color management across digital and print workflows while providing flexible options for handling alpha transparency.
Background
A design system requires all colors to be defined in LCH for better color interpolation in CSS animations.
Problem
The existing brand colors are stored as hex values (#FF0080).
How to use
Paste the hex code into the input field and select 'css' as the output format.
format: css, alphaHandling: ignoreOutcome
The tool outputs 'lch(61.16 93.68 338.27)', ready for use in CSS stylesheets.
Background
A semi-transparent button background needs to be converted to a solid color for a high-contrast accessibility report.
Problem
The color is rgba(255, 0, 128, 0.5) and needs to be evaluated against a dark mode background.
How to use
Input the rgba value, select 'Composite with custom background color', and set the background to #121212.
LCH is a perceptually uniform color space, meaning it aligns better with how the human eye perceives lightness, chroma, and hue compared to sRGB.
The tool composites the transparent color against a chosen background (white, black, or custom) to calculate a solid LCH equivalent.
Yes, the tool accepts hex codes, rgb() strings, and raw numeric values for sRGB inputs.
The 'lch' format uses comma-separated values, while the 'css' format uses space-separated values, which is the modern standard for CSS color functions.
LCH is excellent for color management, but always verify your final output against your specific printer's color profile or gamut limitations.
format: lch, alphaHandling: custom, customBackground: #121212Outcome
The tool calculates the resulting color as it appears against the dark background, providing the correct LCH values for the final design.
