How to do opposite of "PixelSearch"?

[plankton]

While IsArray(PixelSearch(100, 100, 300, 300, 0xffffff))
    Send("{ESC}")
    Sleep(1000)
WEnd

MsgBox(0,"Loop exited","")

Hi, above is my function that will execute ESC button when white color is present in specific area which is color 0xffffff.

But how do I do the opposite like when white color is not present in that specific area? Like this below code which gives me error

 

While IsArray(PixelSearch(100, 100, 300, 300, <>0xffffff))
    Send("{ESC}")
    Sleep(1000)
WEnd

MsgBox(0,"Loop exited","")
