Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  ~ update in-place
  - destroy

Terraform will perform the following actions:

  # github_issue_label.bar will be updated in-place
  ~ resource "github_issue_label" "bar" {
      ~ color      = "FF0000" -> "FFFF00"
        id         = "tfcmt:bar"
        name       = "bar"
        # (3 unchanged attributes hidden)
    }

  # github_issue_label.foo will be destroyed
  # (because github_issue_label.foo is not in configuration)
  - resource "github_issue_label" "foo" {
      - color      = "FF0000" -> null
      - etag       = "W/\"3e945b73323b6ad9f1826356e7f0ad1062c4bdc9a2e09e49d742207ae2b9d338\"" -> null
