@FluorescentHallucinogen I think we would like to keep the current Polymer logo because it's more recognizable. cc @tjsavage

[tjsavage]

Yeah let's keep the Polymer logo. No one really knows the catalog logo.

See the discussion on #282.

I said:

Why https://elements.polymer-project.org uses the Polymer logo instead of Polymer Element Catalog logo in the top left corner of the main page?

@abdonrd said:

Good question.

I said:

do you have original Polymer Element Catalog logo in SVG format to export it to raster icons in various resolution?

@tjsavage said:

We do - just added it to the repo:
https://github.com/Polymer/polymer-element-catalog/blob/master/app/images/polymer-catalog.svg

@blasten said:

We haven't updated those logos yet. PSK, the PolymerElements org and the catalog, all use the old colors. I'd say it's fine to use that logo as it is and in the future we can update it.

that logo = Polymer Catalog logo

@tjsavage said:

Updated the file to make it super flat.

@blasten said:

@FluorescentHallucinogen would you mind updating your PR to use the logo added recently?

I said:

Yes, I plan to update my pull request.

I delete­d my fork and don't know how to update this pull request. (Is it possible at all?) I've created a new PR, see #285.

I keep Polymer logo in the top left corner of the main page. But I think it is a very bad idea to use the same Polymer logo as icons in manifest.json for both Polymer/docs and Polymer/polymer-element-catalog web apps. If the user adds these web apps to the home screen, they should have different icons.

@FluorescentHallucinogen Sorry, I forgot you were originally referring to the logo in top left corner on elements.polymer-project.org and ended up believing you only wanted that logo for the manifest.json. I don't think it's horrible to use the same logo for both web apps because they already have different name. One will say: Polymer Project and the other one Polymer Catalog. Therefore I think it's fine. Again, sorry for the misunderstanding.

Lastly, please update:

• polymer-catalog-logo-32x32.png
• polymer-catalog-logo-512x512.png

One will say: Polymer Project and the other one Polymer Catalog.

Android uses the value of "short_name" key instead of "name" from manifest.json as description for icons on home screen, therefore it displays just Polymer instead of Polymer Project. Also Android truncates long descriptions, therefore it displays Polymer Catal.. instead of Polymer Catalog:

Please also note that icon descriptions may be disabled. If these two web apps will have identical icons it will be very difficult to distinguish them:

That's why I think it's bad idea.

Lastly, please update:

• polymer-catalog-logo-192x192.png
• polymer-catalog-logo-32x32.png
• polymer-catalog-logo-512x512.png

I've alredy updated these icons to new colors. Do you mean change Polymer Catalog logo back to Polymer logo?

You said:

and ended up believing you only wanted that logo for the manifest.json.

I still want use Polymer Catalog logo for the manifest.json.

If we will change Polymer Catalog logo back to Polymer logo for manifest.json, then why we need Polymer Catalog logo at all? It will not be used anywhere. For what @tjsavage updated colors of Polymer Catalog logo?

Are you sure?
