Change attachment color

[gbelintani]

Hi!
I'm trying to change the attachment color at runtime using the same logic I can do in Unity.
I'm using this code, but nothing happens. Am I doing something wrong here?

for (var slot in skeleton.slots){
    if(slot.data.name.contains('Base-')){
      var attachment = skeleton.getAttachment(slot.data.index, slot.data.name);
      if(attachment == null) continue;

      var regionAttachment = attachment as spine_core.RegionAttachment;

      if(regionAttachment != null){
        regionAttachment.color.setFromString('FF0000');
        regionAttachment.updateOffset();
      }
    }
  }

I also tried setting skeleton.color and methods like skeleton.setToSetupPose(); but no luck.
