Reference Talk:Vector Expressions

From question of Bald Eagle in povray.advanced-users, 2016-07-07, that page is missing how to access the fifth component of a 5D vector.
The answer is to see it as a colour: .red, .green, .blue, .filter, .transmit
x,u,red -> 1st
y,v,green -> 2nd
z,blue -> 3rd
t,filter -> 4th
transmit -> 5th
(as a colour, there is also .grey, but that's another story)
The page Vector sends to Numeric Expression, but that one dismiss any details about DOT_ITEM by sending back to Vector / Colour Pages, none of which cover the subject.
