CIELAB

A device-independent color space defined by the International Commission on Illumination (CIE). L* denotes lightness, while a* and b* denote chromaticity axes. Its Euclidean distance corresponds more closely to human perceptual differences and is often used as the perceptual loss space in color transfer.

The specific training pipeline of PREEN consists of two steps: first pretraining a CLIP-conditioned regressor, then fine-tuning with LoRA under an image-level CIELAB loss.

The most distinctive feature of the CIELAB color space is perceptual uniformity, where the mathematical distance between colors (ΔE) is proportional to the color difference perceived by the human eye.
