I’d start with a base of deep moss green, like the ground after a rainstorm. Add layers of charcoal bark brown for the trunks, and a touch of amber for the bark cracks. For the glowing petals, use a soft twilight purple with a faint gold edge so it catches the light. In terms of the story, paint the forest as a living heart: the roots weaving below, the leaves whispering old secrets, and the petals pulsing with the night’s quiet magic. Keep the edges a little blurred, like mist, so it feels alive and breathing. That should give the mural a rhythm that feels like a pulse.
