If you ran the Colorimetry (which means that the color features for each frame are being computed), you can inspect the color features of the current frame you are at in the timeline.
1: The Palette-Visualization of the current Frame.
2: The Space Palette-Visualization of the current Frame.
3: Layer Depth: Defines how “fine-grained” the resolution of the Colorimetry should be. A layer size between 7 and 10 has showed to be most informative.
