Maybe have you noticed that the yellow color is difficult to see on white background, making it difficult to distinguish between the old and young yin, the 6s and the 8s. After several tries, I have resorted to this chart and figured out that I had acceptable results with these two colors, royal and banana. Hopefully this problem is solved now.
The new version of Taoscopy for Android is available. This is the last update before the next major version that will dramatically change the project. The Twitter and Facebook buttons are gone, because Taoscopy now uses Android’s sharing functionnalities. The stability has been improved and other facets of the hexagram are now available such as the pivot method and the patterns of change.
