Few days ago I started playing with OSM-Carto leisure=park colour in Photoshop, because I find it too "crappy" for modern design standards and too blueish. Then I changed @leirure-fill colour to lighter, matching future amenity-fill colour (see: https://github.com/gravitystorm/openstreetmap-carto/pull/3412). I think those are 3 (@amenity-fill, leisure=park, @leisure-fill) areas that should be made more prominent as they are almost always smaller and more interesting city part than eg. landuse=residential or landuse=industrial. I also added possible new colours for landuse=allotments (see: https://github.com/gravitystorm/openstreetmap-carto/issues/3411) and natural=scrub (see:https://github.com/gravitystorm/openstreetmap-carto/issues/2098)
There are many voices that current version of OSM-Carto is generally too pale, so making some elements brighter seems awaited. After changing colours of areas mentioned above, roads became less prominent. There was also some voices on Github, that we should make them brighter, so I tried also with it.
secondary road: f2e76d
primary road: f2c66d
Some before/ after screens (please notice that they are just Photoshop mock-ups to show the idea, so there are small errors like a little bit invalid outlines around footways in parks)

What do you think about this direction for OSM-Carto style? :)
