This rule reached the abnormality threshold, which means there is a real problem you should care about.
This is the colors palette, sized by total occurrences:
Current weight: {{image.originalWeigth | bytes}}
Current weight: {{image.originalWeigth | bytes}} ({{image.originalCompressedWeight | bytes}} compressed)
With a lossless optimization:
{{image.afterOptimizationAndCompression | bytes}} compressed (-{{image.gain | bytes}} compressed)
With a lossless optimization:
{{image.lossless | bytes}} (-{{image.gain | bytes}})
With a lossy optimization:
{{image.afterOptimizationAndCompression | bytes}} compressed (-{{image.gain | bytes}} compressed)
With a lossy optimization:
{{image.lossy | bytes}} (-{{image.gain | bytes}})
