Weal
well-being, prosperity, or happiness: the public weal; weal and woe.
I had the idea of a tree growing out of a half-circle with a V cutout, showing the roots stretching across/into either side. For me, the idea of well-being is strongly connected to personal growth (making this an appropriate companion piece to Solace). The prosperity of the branches is made possible by the roots, and yellow is the quintessential color of happiness.
