Rename positive/negative palettes to be culturally inclusive

[markov00]

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.

Thanks @markov00,

I worked on a product for the Chinese market before and that's where I learned about these differences in the way we perceive colors.

I completely agree that we should rename our palettes to be more inclusive.

I think we should not close this issue, I know that is a major breaking change, but there are reasons for that

@markov00 I noticed that @gvnmagni is working on guidelines for "How to use colors in Data Visualization". It's a good time to look into this issue. I'll connect with @gvnmagni to get his input and guidance.

[gvnmagni]

Totally agree with you all, we should definitely do that. Given also the "Color by term" initiative, this might be a good moment to tackle this as well

👋 Hi there - this issue hasn't had any activity in 6 months. If the EUI team has not explicitly expressed that this is something on our roadmap, it's unlikely that we'll pick this issue up. We would sincerely appreciate a PR/community contribution if this is something that matters to you! If not, and there is no further activity on this issue for another 6 months (i.e. it's stale for over a year), the issue will be auto-closed.

@gvnmagni @markov00 Any chance either of you would have time to contribute to EUI to help get this done? I can re-open if so, but I'm not totally sure when else we'll be able to prioritize this as a team.

[gvnmagni]

Let me talk with Marco about this, I'll get back to you!

After thinking about this a little, I would personally avoid using any term that can be associated with anything different that the color itself. We do have Cool and Warm palette, but I think that they can work since they refer to something that naturally happen and that it's not related to anything "cultural".

As we have the Gray gradient, I would suggest to rename these as Green and Red in order to avoid any possible assumption.

@markov00 please feel free to add anything if you think it's relevant, but I believe this will solve this issue pretty quickly and protecting us from future additional conversation around meanings. Also, the new color mapping feature will help us when dealing with gradients, once adopted in all places
