ee at_ vs ee aa

How would you tell the difference between these two?

Thanks much.

at_ee will be light in the areas that are light on an otter/martin at_E_ but tort in the areas that are black on an otter/martin at_E_. So it will have tort markings on its face and flanks but white eye circles, white inside the ears and a white belly. These areas should be dark on a tort.
eg at_ee vs aaee
EDIT: Added the tort for comparison.

Thank you that is exactly what I needed to know. I was trying to look and pictures but most didn't show the belly.
