Sikkens Translucent vs Semi-Transparent

I couldn't find this info anywhere on the web, so I'm laying it out for you here, for posterity's sake: you can see more underlying wood through Sikkens Translucent than through Sikkens Semi-transparent.  To put it another way, Semi-Transparent Sikkens blocks more light, so you can't see the wood grain as easily through it.  Home Depot had finished pieces of wood in the 3 finishes Sikkens offers there (Translucent, Semi-transparent, Solid).
