I've always felt that the GD way of coloring the banners was wrong and took an interest in the Vision of the Round House which seems to depict the Great Table.

This is what I came up with:
Read on to find out why I used this instead of the more traditional way.
Round house:
sides east south north west
doors white red black green
indoors red grey d.grey white
element fire air earth water
It hath four Doores, and at the East Doore is one step, at the South two steps, and at the North three, and at the West Doore, four steps. The first Doore is white, like Chrystal, transparent: the South Doore is red of an high colour, transparent. The North Doore is bright black, not to be through seen, as the rest. The West is green, like an Emerauld Stone: So is the South Doore like a Ruby.
The Doores be all plain.
East Door: KELLEY: Note the colour of the fire of the four arches, is very red; the rest are very pure, Ariel, candent, etc.
The Motion of the trunk fire is swiftest.
West Door: KELLEY: The colour of the water in the Center, is most pure white.
North Door: KELLEY: Now he openeth the black bright Doore; and the House there seemeth full of black dust, like Gun-powder colour, or somewhat of Leadish colour.
South Door: Now he openeth the red Doore.
The House seemeth darkish, of colour of the smoak of a Wax Candle being put out.
One thing to note though is that neither the original Great Table or the reformed edition have the same placing of the tables as the ones in Dee's drawing above, where I took the directions of the banners from.
Comments and criticism is appreciated, I hope there aren't too many errors.
Here's a good source of info on the subject as well:
