ChatGPTで描く、色が映えるポップイラスト｜プロンプト7選｜画像生成AIの5ツールで比較【Niji Journey・SeaArt・Grok・NanoBanana】

おはようございます。Kinuです。
遊びに来てくださり、ありがとうございます✨

今回は、色が映えるポップなファッションイラストをテーマに、
私が実際に使っているプロンプトを7つご紹介します。

そのままコピペして使うのはもちろん、髪色や服装、配色を変えるだけでも、自分好みの雰囲気にアレンジできます。

そして今回は、ChatGPT、Niji Journey、SeaArt、Grok、NanoBanana
それぞれで生成して比較しています。

同じプロンプトを使っても、線の雰囲気や色の出方、イラストのタッチが少しずつ違うのが面白かったです。

「どのツールを使おうかな？」と迷っている方にも、
参考になれば嬉しいです✨

◆最後に

最後までご覧いただき、ありがとうございます✨

今回は、色が映えるポップイラストのプロンプトとあわせて、同じプロンプトを複数の画像生成AIツールで試してみました。

実際に比較してみると、同じプロンプトでも、「色の出方、線の雰囲気、表情、全体のまとまり方」など、ツールによって少しずつ違いが出るのが面白かったです。

今回の生成結果では、私はNanoBananaとnijijourneyの雰囲気が特に好みでした。

ただ、「どのツールが一番良い」というよりも、自分がどんな作品を作りたいかによって、ツールを使い分けるのも一つの楽しみ方なのかなと思っています。

皆さんは、どのツールの雰囲気が好みでしたか？

ぜひ、好きな色や服装、小物にアレンジしながら、自分だけのポップイラストを楽しんでみてください✨

これからも、プロンプトや実際に使って分かったこと、
ツールごとの違いなども少しずつ共有していきたいなと思います。

今日も素敵な一日になりますように✨
