Forest Gradient

A quiet color field transitions from dark pine green through fresh lime into pale yellow.

Dark pine green is the strongest starting zone, with lime and pale yellow gradually taking over. Sort by lightness first, then compare the direction of the color shift along each piece. Smooth fields can be deceptive at high piece counts, so short confirmed runs are more reliable than large guesses. The details around forest gradient give the picture enough landmarks to keep the quiet areas from feeling empty.
