Rgba to Hex

export function rgba2Hex(color: string) {
  const rgb = color.split(",")
  const r = parseInt(rgb[0].split("(")[1])
  const g = parseInt(rgb[1])
  const b = parseInt(rgb[2].split(")")[0])

  const hex = "#" + ((1 << 24) + (r << 16) + (g << 8) + b).toString(16).slice(1)
  return hex
}

Hex to Rgba
