- Tap 'Adj pix mat ref pt color'.
- Tap the petal as the reference point
- Adjust RGB. The color may change, but only a part of the object.
- Adjust TR, TG, TB. The T stands for Tolerance. After increasing the values, you can see the adjusted region is expanded. Now it's possible to adjust the entire petals of the flower.

Unfortunately, the flowers of the weed(white dots) are also white. The colors are also replaced with orange. Is it possible to limit the effect region?

Delete the reference point, start all over again.
