You need the base for the darkest colors, in many cases this is called #4 (I think Olympic may call it #5) and some just call it "deep color base". While most of them dry clear, not all do. I have always used an oil base exterior (mostly Olympic) but can't get it anymore. I also bought some Olympic exterior acrylic enamel (water clean up) and found it to dry clear...but they've changed the names of their paints and I don't know what the current label is. If you have a SW nearby, you can probably find their base in oil and at least one can of it that I had dried clear. But it's mostly guess and hop, although most of them (I suspect) do dry clear.
I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.

IIRC Sherwin-Williams' clearest is called ultra-deep base. So don't just ask for "deep base."

There are reports on the web that a "deep base" (no color added) makes a good clear finish for exterior use. I did my own unscientific test a while back using the SW "All Surface" oil base paint base. I applied 3 coats on a piece of pine and left it in full sun and weather exposure. After about 3 months, the finish was completely destroyed. About 50% of it was gone and the rest was curled and ready to flake off. If the OP is planning on using a similar product for exterior exposure, I would suggest that he do his own test before he uses it on his project.
