background color or theme color doesnt change

[Mike-Van]

I just tried this out in my gatsby project, and im really happy that it works, but the problem is that my favicon.png is white, so i try to change the background color to use custom color, it doesnt work. I refresh the site, rebuild the site. But still it doesnt work. Please tell me how to fix this.

{
      resolve: `gatsby-plugin-favicon`,
      options: {
        logo: "./src/favicon.png",
  
        // WebApp Manifest Configuration
        appName: null, // Inferred with your package.json
        appDescription: null,
        developerName: null,
        developerURL: null,
        dir: 'auto',
        lang: 'en-US',
        background: '#6bc4bc',
        theme_color: '#fff',
        display: 'standalone',
        orientation: 'any',
        start_url: '/?homescreen=1',
        version: '1.0',
  
        icons: {
          android: true,
          appleIcon: true,
          appleStartup: true,
          coast: false,
          favicons: true,
          firefox: true,
          opengraph: false,
          twitter: false,
          yandex: false,
          windows: false
        }
      }
    },

Thanks for the report! I have to admit that I don't know the expected behaviour of this option. I'm only relying on the underlying plugin favicons to handle it.

Can you paste your original favicon.png?
