Why are CYAN and MAGENTA included as colors?
The colors included within the palette are the names for hues that most humans perceive. The various shades and values within these hues actually range in saturation and intensity, therefore you may see PINK nodes fall under the RED category, or DARK BLUE nodes fall under both BLUE and CYAN. This is just the manner in which the backend was built so that colors could be analyzed and then represented in text form for filtering.
