Thanks for reporting. This is unexpected as v0.3.7 was intended to fix color problems: https://github.com/mapbox/mapbox-studio-classic/blob/mb-pages/CHANGELOG.md#037. There are two known regressions recently fixed: https://github.com/mapbox/carto/issues/442 and https://github.com/mapbox/carto/issues/443. Can you see if you can isolate what else changed and create an issue at https://github.com/mapbox/carto/issues? /cc @nebulon42
Also can you isolate which version of studio changed things? It is possible this is a carto regression but also possible it is due to the node-mapnik upgrade. See https://github.com/mapbox/mapbox-studio-classic/blob/mb-pages/CHANGELOG.md for when things changed.
Attached are the styles as generated by versions 0.3.4 -- 0.3.7: v0.3.4 - last good version, no changes compared to previous ones 0.3.5, 0.3.6, and 0.3.7 each introduce different changes in colors, each differ from others, and each looks wrong in different ways.
@nyurik thanks. So in v0.3.5 both node-mapnik and carto were upgraded. So I've done a test build with upgrade node-mapnik but downgraded carto. If this one works that will indicate carto regressions. Can you test it:
1) go to https://mapbox.s3.amazonaws.com/mapbox-studio/index.html
2) Download one of the be65824
builds per your operating system.
My tests indicate a problem with colour multiplication (e.g. #f8f4f0 [=land] * 0.8). I'm at it, but I can't rule out that there are other (additional) problems.
@springmeyer osm-bright.tm2 should also be affected, maybe you can confirm. I couldn't get mapbox-studio-classic to run properly.
@springmeyer I tested your build, and it works perfectly (not a single line has changed). Also, you can easily test it yourself - it uses our public pbf tiles from maps.wikimedia.org. To test, I open that style in the studio, hit Save, and do a git diff
in the repo. Lastly, I'm now in the gisdevs.slack and irc in case you have a direct question.
git clone https://github.com/kartotherian/osm-bright.tm2.git
cd osm-bright.tm2
npm install
The problem is that 0.8 is another colour in RGB than in HSL (that's how colours are now represented internally). My personal opinion is that something like #f8f4f0 * 0.8 does not really make sense. Since we have to maintain backwards compatibility in all cases a fix is needed, but I think it will be getting a bit hackish. I will simply treat all single values that are converted to a color as greyscale RGB representations.
Carto problem should be fixed upstream.
Our repo kartotherian/osm-bright.tm2 gets badly messed up when editing with MBS v0.3.7 - many roads change color to pinkish. The repo was mostly updated with versions v0.3.1 and before, without any issues. cc: @MaxSem @springmeyer
