Frequently Asked Questions

Common questions about LCH channel extraction

What is LCH color space?

LCH (Luminance, Chroma, Hue) is a cylindrical transformation of the CIELAB color space. It is more intuitive for humans because it separates color into brightness, intensity, and hue.

Why use LCH instead of RGB?

RGB is hardware-oriented, while LCH is human-oriented. LCH allows for more precise and perceptually uniform color adjustments, which is critical for professional design and accessibility.

Is the extraction accurate?

Yes, our tool uses standard mathematical formulas for RGB to CIELAB and then to LCH conversion, ensuring high precision in channel separation.

Can I download all channels at once?

Yes, the batch processing feature allows you to extract channels from multiple images and download them as a single ZIP file.
