@KaFu how do it works fine to you, if the hex $icolor valor returned in the msgbox is always 0xF0F0F0 independent of the value set in "xxxx" ?

GUICtrlSetBkColor($text, xxxx)

You are right, didn't realize that mixed up f2f2f2 and f0f0f0 ;). _WinAPI_GetPixel 0,0 seems to catch the border of the button, so getbckcolor needs to be adjusted by 3,3 to capture the buttons background. It get's even worse with an Input control, where the default will capture the input caret. So depending on the control type this one still needs more tweaking.

#include <WinAPIGdi.au3>

$h_GUI = GUICreate("# WINDOW #", 200, 200)
$c_button = GUICtrlCreateButton("TEST", 40, 34, 90, 90)
GUICtrlSetBkColor($c_button, 0x000000)

$c_input = GUICtrlCreateInput("test", 10, 130, 180, 20)

GUISetState(@SW_SHOW)

For $i = 0x000000 To 0xffffff
    GUICtrlSetBkColor($c_button, $i)
    GUICtrlSetData($c_input, Hex(GUICtrlGetBkColor($c_button), 6))
Next
