Making pitch and track color less dominant

[kocio-pl]

Resolves #1190.

The color definition is not absolute for now to make it easier to test modifications. When it'll be ready to merge, I will remove the "[WIP]" (work in progress) from the title.

After some testing I feel this color (lighten 8%, desaturate 5%) is the best on typical backgrounds:

z14 - it's still visible on the sport center and on the ground, but less than a forest, and small spots on residential area are not a problem now:

After

z15 - pitches are less intense than a special building and secondary roads, now they are more or less like a regular buildings, which is good:

After

z16 - when school areas are bigger, it's the same as with sport centres, and we have a special case, pitch on the residential area, which also looks OK on this zoom level:

After

z17 - another typical background, pitch on a grass, you can also see that it's still much different than cemetery green:

I'm going to merge it if in a few days if no one will oppose.

This does not seem to be codified here i think but it is generally not common to merge your own changes (4-eyes principle).

I am staying out of this matter due to #2270.

The current color by the way was selected in #2071 after #1190.

This happens sometimes (like in #2409), but I definitely won't push anything when there are any objections.

I consider it to be rather objection than just lack of interest, so now I don't plan any action here.

No, you shouldn't merge this without review from someone else

Neither is the case - i am just not able to form a qualified opinion here. I would not change the color this way but i would also not have changed the playground color the way it was changed or the dog_park color. So i can't really say if i consider this change in isolation as good or bad.

So i am fine if this change finds general approval - but i would appreciate it of course if - in line with #2270 - someone can explain the guiding principles behind these color choices then.

I commented on that in #2436 (comment), but my message likely crossed your message (and @kocio-pl's comment). Of course, everything is open for discussion, but let's keep discussing the principles separate from discussing this PR.
