I was just wondering how much a VB2 translucent ball would pick up lighting from surrounding controls, such as EI2 buttons and trackball? In this case, "sapphire gemstone" would be installed on silver shafts on the blue pill CP with 16 GGG EI2 buttons shining blue.
They would go on this, with an EI 3" trackball with RGB drive running blue as well:
