No problem at all! Let’s replace “Gentle Aqua” with a blueish-green shade that fits well with the rest of the palette. A suitable option could be “Teal Blue” or “Seafoam Green,” which will harmonize nicely with the existing colors.

Here’s the updated palette with “Seafoam Green”:

1. Soft Blush - #E1D3D0
2. Cool Mint - #A6D3D4
3. Seafoam Green - #A3D3D2 (new color)
4. Deep Teal - #008C8D
5. Dark Forest - #005A5A
6. Mysterious Pine - #003D3B

Here’s the revised JSON for the updated palette:

                        "
    }
  ]
}

The “Seafoam Green” will maintain the blueish-green theme while providing a lovely transition between the colors. Would you like any further assistance with your mural design or other ideas?
