sub color white and lighter background is the most brilliant.
After the particle is drawn on the layer which was added to the emission, it increases the light emission when one piece of gaussian blur is applied and it copies it. Then duplicate it and overlay it or experiment with the desired lighting condition.
サブカラー白と明るめ背景が一番キラキラ
加算発光にしたレイヤーに粒子を描いたあとコピーまたは複製→そのうち一枚ガウスぼかしをかけると発光増します。さらにそれを複製して重ねたり好みの発光具合を試してください
