There is no heat map/color difference pytest-needly using PIL

[rafeekabid]

Team,
I’m using pytest-needle 0.3.11 using PIL engine to evaluate visual testing. Everything working as expected but in report unable to find the colour difference in the diff screenshot. In report, its showing actual screenshot, expected screenshot and difference. But unable to identify what is the difference. Is there any solution to get heat map (color) difference between two screenshot.

Thanks in advance and looking forward your support.

Regards,
Rafeek
