Based on your request to update the “Jujutsu Kaisen Cursed Energy” palette while maintaining the overall theme, I suggest the following updated color palette:

• Cursed Energy Blue: #1E90FF (unchanged)
• Sukuna Red: #FF6347 (a softer red)
• Hakari Green: #2E8B57 (a deeper green)
• Cursed Purple: #6A0FAD (a brighter purple)

Here is the updated palette in JSON format:
