Absolutely! If you’re looking for a less saturated green that leans more towards blue or orange, I suggest the following:

1. Bluish Color: HEX 4A9BC4 - This is a softer, more muted bluish-green that harmonizes well with your existing palette while maintaining a calming effect.

2. Orange-related Color: HEX D3A36A - This is a warm, earthy tone that has an orange undertone, which complements the warm orange already in your palette without being overly saturated.
