[Discussion] More than two team colours during tournament

[Debilski]

I just had this weird thought: What if we allowed for more than just red and blue colours in the UI? Especially (or perhaps only) during the tournament. It would certainly make it easier to find one’s team on the map when each group has a colour they are supposed to identify with.

In 2018 we already used 5 different post-it colours to indicate to which group a laptop would belong to and when we presented the repo statistics (which team had how many commits and at what hour), I tried re-using the same colours in these graphs to make the connection more obvious.

I guess the food could still be red and blue, we’d just colorise the bots differently during tournament (if we find enough good looking colours or colour combinations).

Any thoughts on this?

As long as the palette is colourblind friendly...

Anyway, I'm neither in favour nor opposed to this. It is fun but it does add another point of failure (how do you control the team/colour matching, if it's the team's responsibility how do you ensure they're all different... etc.)

it seems to me this is a nice-to-have but certainly in the back of our priority list with pelita. And, if we ever go for it, then food should be colored accordingly, so that each game is consistent and understandable on its own outside of the tournament. In order to find five colors we could of course get 5 equally spaced colors on the viridis color map to be on the safe side, no? By the way @jni, are red and blue color-blind friendly enough?

With regards to the colours: there could be variants that draw a border around the bots as well (needs to be projector friendly: we cannot do yellow on a white background) and therefore we’d basically have two colours for each bot (that could be the same, if a border is not needed). If get really crazy, we can also do striped versions.

For the tournament, I would fix the colourscheme in the tournament config (either free-form or with a pre-defined palette of good colours). The users have no say in it.

Sure, it is very low priority, but I didn’t want to forget about it. :)

Tested on https://www.color-blindness.com/coblis-color-blindness-simulator/ , if its not Monochromacy/Achromatopsia, then the blue at least stands out a little. But I don’t really have experience in interpreting this data. (I think we would have gotten complaints though, if it were too bad.)

As I understand it red/blue is ok contrast, and orange/blue is the best contrast you can get for most people. For many colours we can use the seaborn colorblind palette:

You can do a lot better than viridis if you don't have the restriction that colours have to be sequential...
