Don´t anybody knows how to change color schema of tiled basemap in color PNG?
The one way is make new mapservice created as a clone of original mapservice, convert all tiles to grayscale PNG and save them instead of original color tiles. But I am looking for solution to display color tiles in grayscale using some filter or somethink like this. Can You help ?

Thank You very much. Could You implemet it to FlexViewer 2.4 ?
I´m not programmer, so I don´t know to implement Your code to 2.4.
I suppose Your code is for index.html in FlexViewer version 1.x, but version 2.4 seems different.
Can You help me with implementation.
Thanks in advance.
