There are some resistors that are difficult to read. For example White body, White tip, and Red dot. That would read 9900 = 9.9K Ohms But if you read it as an orange it would be read as 990,000 ohms or 990Kohms. Now here is one issue with Philco, sometimes the colors were a little bit off color, so a red may be actually an orange and vs/vs.
They also had two different colors for Gray (Grey) one was battleship grey and another type which I forget at the moment.
So even shades of colors could be non-consistent. Now here another issue in the three page beitman of the model 19-128 they list a white, white, orange as a
100Kohm in the resistor data table 3. Riders volume 4 section 4-pages 18-19-20 part #45.
So evidently they didn't follow a set of colors such as RMA. Strange (well its close to 99Kohms and well within 20%) so go figure.
The best way is to measure and see how close to the colors they are if you can't follow a schematic.
I have seen what you say as half one color and half another color but have found no explanation. If there were just one color then that color would be probably a cap rather than a resistor (that's just my opinion so don't rely on me)
