Three state colors in schema and data title panels instead of two.

Change title color states from Green/Red to Green/Orange/Red to increase user intuition friendlies.

• Scheme:

Green: Valid json structure, valid draft structure
Orange: Valid json structure, invalid draft structure
Red: invalid json structure

• Data:

Green: Valid json structure, valid by schema
Orange: Valid json structure, invalid by schema
Red: invalid json structure

Interesting. Would welcome a PR to see the effect.
