According to your oversold to overbought diagram, it looks like financials and Health care are both overbought and the strongest sectors.
While scrolling through the information on the site of Tom Dorsey (DWA), I have a different reading...

DWA distinguishes 40 sectors (!). The strongest sectors are
1 Biomedics favored
2 Aerospace average
3 Drugs favored
4 Healthcare favored
5 Restaurants favored
6 Leisure favored
7 Semiconductors favored
8 Housing favored
9 Textile favored
10 Insurance average
...

Financials are ranking #13 and are unfavored (in this case, for example the percent of stocks in positive trend is bear confirmed and the RS trend of the sector is not giving enough positive signals). In the data table 'stocks above 150 day moving average' financials are #1 and going up ?!

On the sector bell curve (the 40 broad sector groups are mapped according to their current bullish percent reading, that is the percent of stocks on a P&F buy signal), financials are in the middle of the curve @48-52% and not really shifting to left or right at the moment. In the visual diagram, financials are in the 70-802% zone and green?

Firstly, you're comparing the major industry groups in my sector breadth with the individual subsectors in Dorsey's bell curve. So you will see differences, as the Financials sector in my sector breadth is made up of 1160 stocks currently out of of a total 4829 stocks. Which is 24% of the whole market, so it's by far the largest industry sector and is obviously made up of many subsectors. Health Care currently has 578 stocks, which is 12% of the market and of it's subsectors will be Biotech stocks that are leading in the Dorsey bell curve. So what i mean is, is that you are comparing industry sectors with subsectors.

No sectors are currently overbought on the visual diagram. So I'm not sure why you are seeing that, as the visual diagram says what they are on the right hand side. So for example Financials and Health Care are both in the Bullish range in the visual diagram. And health Care has been been in a strong uptrend since October.

Here's the current standing on the visual diagram:

4 sectors are in the Bullish zone
2 sectors are in the Neutral Positive zone
1 sector is in the Neutral Negative zone
1 sector is in the Bearish zone and finally
1 sector is basing in the Oversold zone

So we have 6 out of 9 in the positive zones currently, and a total of 53.51% of 4829 stocks in the US market above their 150 day moving averages. So an overall market reading in the Neutral Positive zone. Which matches up with the NYSE and Nasdaq Percentage of stocks above their 150 day MA readings which I also include on the visual diagram for comparison.

As for the colours on the chart, they simply show the weekly direction, as highlighted on the table as well, and are not specifying trend.
