We have two single hues, sequential, color palettes named Positive and Negative

The same naming is also reused within Kibana, in the color palette dropdown menu for visualization (lens/visualize)

The reason is that the association of green = Positive and red = Negative are mostly a western region type of association, where some eastern regions use the opposite association, where green = Negative and red = Positive.

Just take a look at the Japanese stock market:

I'd like to propose a name change, toward culturally neural names, like Greens and Reds or something similar.
