But in OEL, the top left and top right borders are curved, so there is a possibility of error if we directly compare those points with GREEN colour, that's why an OFFSET is needed. But an OFFSET of 2 is not sufficient for OEL, and for safety I will change it to 5. I don't see this issue in Ubuntu as the borders as rectangular there, but not curved.
