Pressure settings not working correctly

[theserpent]

Well guys color pressure doesn't work fine i.e it should be darker shade of color when pressed hard and when pressed lightly lighter shade of color.But this is not happening .
Well shape pressure works fine(Thin line to fat line)

Am also using wacom bamboo one. You should probably have to Calibrate BRUSH settings. Maybe a silly answer, but try updating DRIVERS.

I guess, it will help you.

^^I don't know what you mean by that?

For first query you need to turn on pressure control for opacity .. you can find it in either command bar at top in right side of opacity or in brush panel under the name of "transfer"

I've seen thick-to-thin stroke by the pen tip pressure. But this, Strong-to-mild color change is new to me.
