The Spirit changes colour throughout seasons as well as Amber's clothes, my idea was to give Amber pastel-like primary colours and the Spirit secondary colours as well as appropriate colours for the scene/seasons, so Autumn is warm and orange (but red when danger is near), Winter is cool, clean and blue, Spring is fresh greens filled with colourful flowers and Summer is hot and rich in greens, blues and yellows.
It's important as well for these colours to complement the backgrounds as well as each other, so I will have some colour/mood sheets for those too.
