There are tint families for warm white (LCW), white (LW), and ultrawhite (LUW) which is a cool white. The warm white and ultra white families sometimes seem to follow ANSI White with each ANSI White quadrangle broken up into a number of subgrids (it doesn't seem to be their intention to be able to bin by individual subgrids but by groups). The grid has numbers which are vertical subdivisions and letters which are horizontal (they follow the color temperatures; for instance, 6500K is divided into vertical bands C,D, and E while 5700K is divided into F and G) as follows:
