Comparison with the rest of the colors in this style

I will not oppose this change if it finds support by other maintainers but i would strongly advise against it because it would go against almost every concept of systematic color design we have followed or considered in the past.

The logical alternative would be to roll back #2363 (and it might be helpful to read up the discussion that led to that choice in #2071 - which contains some of the considerations regarding systematic color choices i consider important). You could also have a look at the ac-style which uses #88e0be - although that is designed to work together with other changes, in particular a distinct color for playgrounds.

This proposed color, as noted, is almost the same as the allotments color. Similar colors should have similar meanings. Allotments are not very similar to sports tracks or pitches, so this proposed change is not a good idea. #88e0be looks interesting. I would also suggest looking at #b8dabd

Any change in pitch color is going to have to account the color of the landuse below it and IMO this color makes the current color for parks stand out way to much. Especially at z17.

We should not have 2 colors that are only barely visually different. In the unusually case with a pitch and allotments overlapping or adjacent it will be hard to see the difference. The differnence between the new pitch and current allotments is only Δ: 4.3 in Lch, which is not enough to be clearly understood.

However, we cannot simply unifiy the color with that of allotments. Similar colors should have similar meanings. Allotments are not very similar to sports tracks or pitches.

Alternatives that could be accepted would be to pick a different new color for pitches which was not too similar to another color. As mentioned above, #88e0be might work. I would also suggest looking at #b8dabd.

Another option would be to change the allotments colors. These are similar to farmland and gardens, but also sometimes related to residential areas. I could be challenging to find a better color, we have already changed it 3 times (see #2267, #3625 and #3548) - so I would recommend trying a different pitch color instead.

I've updated the color to #88e0be per your suggestion. The images in the initial comment have also been updated.

I had not noticed this had been changed to use the color from the AC-style. This seems fine to me now, maybe a tiny bit too strong because OSM-Carto uses somewhat weaker colors overall than the AC-style. But that is something that should be reconsidered anyway (#3647) so this is completely fine as a subtle move in that direction.

I am sorry for the long time it took to review this - it somehow slipped my attention.

Review was about different color
