Any gauge will do, the currents are small. Even AWG 26 is plenty. So anything that Daze sells, the smallest gauge, is good.
As for the colors, are you doing a museum quality restoration? If not, just use whatever colors you use for wiring the chassis, and enough variety to discern when twisting together 3 or 4 of them.

For what it's worth, here's what I do.

I use the 20 gauge stranded "small profile" cloth-covered wire from Radio Daze. Years ago, I decided to standardize on the 1932-36 Philco speaker wire color codes, or as close as I can get to them since we can't buy wire that has the contrasting color of tracers woven into the cotton covering - we can only purchase solid colors - as follows:

Single-ended outputs:
Green - Output plate to audio transformer
White - Output screen grid to audio transformer and one side of field coil
Blue - Other side of field coil (original color was green with white tracer)

Push-pull outputs:
Green - One output plate to audio transformer
White - Other output plate to other side of audio transformer
Blue - Screen grids or B+ to center tap of output transformer plus one side of field coil (original color was green with white tracer)
Any other contrasting color (red, yellow, orange) - Other side of field coil (original color was blue with white tracer)

I hope that makes sense.

Just a quick tip.  I get white cloth covered wire, and "color code" it with Sharpy permanent markers.  They come in just about every color.  Easy to just put a trace line down the side, or color the wire piece completely.  Cuts down on stocking several spools of different wire.  Take care, Gary
