That might work. Unfortunately abbreviations are forbidden by the Google Style Guide.

> As for lining up

my point still holds. Either lining up helps or it doesn't. If it doesn't help then lining up comments should not be allowed. If it does help, then it helps every where.

    var infos = [
      { name: "red",   value: [255,   0,   0, 255], },
      { name: "green", value: [  0, 255,   0, 255], },
      { name: "blue",  value: [  0,   0, 255, 255], }
    ];

Is vastly easier to read and find errors in IMO than this

    var infos = [
      { name: "red", value: [255, 0, 0, 255], },
      { name: "green", value: [ 0, 255, 0, 255], },
      { name: "blue", value: [ 0, 0, 255, 255], }
    ];

The first is not allowed by the Google Style guide. It requires the 2nd.
