I see that 1/144 Direct has roundels in the ratio 1:2:3 and 1:3:5. Can someone explain what that means?

So how many books are in your personal library?
1:2:3 - distance from central point, so the central spot appears quite large (one third red, one third white, one third blue for R.A.F.)
1:3:5 - the central spot appears quite small (one fifth red, then two fifths white, then two fifths blue)

WW2 "thin white" roundels with thin yellow outer edge are 3:4:8:9 (3 ninths red, one ninth white, 4 ninths blue, one ninth yellow)
The ratio refers to the proportion of a straight line taken from the central point to the outer edge.
Thus a 1:3:5 roundel 30 inches across edge to edge would have a three inch red, surrounded by a six inch band of white, then a six inch band of blue, measured from the central point to the outer edge.
Note that the central red spot would be SIX inches across (three inches either side of the central point).

Nice site Tim, I had not stumbled on this one before.
Wikipedia can - and it'll tell you when they were used !
