Well, not pure cyan (at full saturation). It doesn't get multiplied with a pure red either (220,21,61).
I said none of the colours are seperated into channels or subtracted. If you multiply a colour with pure white it will simply be the colour as if it never got multiplied ( x,x,x * 1,1,1 = x,x,x).
To add subtractive doesn't fit when it is not the right term.
What is subtractive blending?
Subtractive blending just subtracts the colour from the image and mostly leaves the remaining colours.
For example: An image with rainbow gradient gets subtracted by pure red. All colours that contain any red values get subtracted leaving only blue or green colours and making red colours black (1,0.5,0.3 - 1,0,0 = 0,0.5,0.3)

Don't care about the side note. It was just a finding when I checked taiko-glow.png being multiplicative or additve while leaving my lighting as that giant ring.
