i try to convert a argb value to a rgb-value without losing the information it got from his background.
so for example: the background is black, the argb is (150,255,0,0) and as the result i wan’t to have a kind of brown.

is there any chance to deal with that?

    You may calculate

    foreground * alpha + background * (1-alpha)

    as your new color for channels red, green and blue. Note that I used an alpha scaled to 0 to 1 in the expression.
