COMPUTEDAn orange core, then purple, green, yellow, blue and red, then the void. With red, 7 of Dave's 8 q.d colours are present. Black is the void; white is the only one missing.

COMPUTEDRed is the long-wavelength edge of vision. The CIE ȳ sensitivity falls by roughly a thousand between 650 and 750 nm, so the red shell really is the last light before the void. Tap "mix all shells": the six coloured shells, added as light, land near white. The missing eighth colour is made by the other seven, with no new ingredient (the weights are solved for).
