[solved] [libGdx] Why sprite.setColor() doesn't work ?

Hello everyone ;D !!!

i have a quick question about tinting a sprite, so i have a white circle PNG image, which i want to draw it in different colors.
In the Wiki, the closest and most “legit” thing to use is sprite.setColor(theNewColor), however this doesn’t work, so i found myself forced to use spriteBatch.setColor(theNewColor) then go back to the default color after finishing drawing the object.

My question is, why the first approach doesn’t work ? (i tried it in the Create method and also in the Render method)

thank you

(very happy to ask here again ;D )
