I've used EM9300 and EM8000cv. Both are fairly easy to apply. I find the 8000 a little bit easier. The polycarbonate 9300 is whiter going on. IMHO, the yellow of the 8000 - even with the cross linker (which I recommend) doesn't skew the shade enough to make it appear amber or yellow like an oil-based finish would. It's a pretty natural look.

The way to really achieve a "no finish' look, IMHO is to use a matte sheen for whichever product you choose.

I would not mess with adding a pigment or another additive to it. I would try without, and see how you like it. I am willing to bet you won't feel the need to adjust the tone.
