Color Palette Analysis
Saturation & Color Diversity
Analyzes color distribution including saturation levels, color diversity, and white balance consistency. AI images often have oversaturated colors.
Frequently Asked Questions
What is color palette analysis?
Examination of color distribution including saturation levels, hue diversity, and color balance across the image to detect AI generation artifacts.
Why are AI images oversaturated?
AI models are often trained on heavily edited images with boosted colors. They learn to replicate this "enhanced" look, producing colors more vibrant than typical camera output.
What is color diversity?
Measured using hue histogram entropy, this indicates how many distinct colors are present. AI images may have artificially limited or exaggerated color variety.
How is white balance checked?
By comparing color temperature (red/blue ratio) across image regions. Real scenes have consistent temperature; AI may have unnatural variations.
Can post-processing fool this?
Yes, color grading can normalize AI colors. This is why color palette has low weight - it's a supporting indicator rather than definitive proof.
What saturation levels indicate AI?
Mean saturation above 140 (on 0-255 scale) suggests AI generation. Most camera photos fall in the 40-100 range without heavy editing.
Does this work on black and white photos?
Color palette analysis is not applicable to true B&W images. Other detection methods handle grayscale content more effectively.
What about stylized/artistic photos?
Heavily stylized real photos may trigger false positives. The low 3% weight prevents this from significantly affecting overall detection accuracy.
How is saturation uniformity analyzed?
Real photos have varying saturation based on lighting and materials. AI often produces unnaturally uniform saturation across different objects in a scene.
Can this detect specific AI models?
Different AI models have different color biases. Midjourney tends toward vibrant colors, while Stable Diffusion versions vary. The detector looks for general non-natural patterns.
