✅ How can I convert/flatten an 8-Digit Hex color (Alpha) to a 6-Digit Hex color (Assuming white BG)

Does anyone here know how to convert an 8-Digit HEX color code to a 6-Digit HEX color code (Assuming the background color is white)? For instance #8F8C7E00 should resolve to #FFFFFF (Because the first hex is completely transparent as the last two digits are 00.) I've attached an image that elaborates. Also have a stackoverflow post here that goes into more detail: https://stackoverflow.com/questions/78044876/how-can-i-convert-flatten-an-8-digit-hex-color-alpha-to-a-6-digit-hex-color-th Any help at all would be extremely, extremely, appreciated!
