How to color and remove emphasis on item names?

I am currently making a remake of the Cobalt Shield in Minecraft 1.14.3, but I do not know how to change the custom item name's formatting in-game.

Can someone help me figure out how to color the item name and make font adjustments to it, i.e. make it non-italicized?

I tried to use this command:

/give @s minecraft:shield
{
  BlockEntityTag:
  {
    Base:11,
    Patterns:
    [
      {
        Color:9,
        Pattern:"vhr"
      },
      {
        Color:15,
        Pattern:"cs"
      },
      {
        Color:15,
        Pattern:"ms"
      },
      {
        Color:4,
        Pattern:"sc"
      },
      {
        Color:15,
        Pattern:"gru"
      }
    ]
  },
  AttributeModifiers:
  [
    {
      AttributeName:"generic.knockbackResistance",
      Name:"Block",
      Slot:"offhand",
      Amount:100,
      Operation:0,
      UUIDMost:71140,
      UUIDLeast:113080
    }
  ],
  Unbreakable:1b,
  display:
  {
    Name:"{\"text\":\"Cobalt Shield\"}"
  }
}
