Change ARGB color int's single channel value

Question

If I have a color:

int color = 0x1a2cf3bb; // just an example

How can I change, for examle, just the R channel with the value:

int red = 0xfe; // another example

So that color becomes:

color = 0x1afef3bb;

Answer 1

int result = (color & 0xff00ffff) | red;
