Lesser with yellow belly

Hi I pick this guy up, is it normal for them to have a yellow belly?

He also has some nice silver looking blushing on him. And eyes like a pastel.

I've only seen to lessers in person but they were both different to this one. Not saying its anything other than a lesser but maybe a bit different.

Some snakes have that... I have a couple that have off white/Yellow belly. Could be getting ready to go into shed also

When Lessers start their shed the belly turns a yellow/brown tint...

I was thinking he was going into shed as well.
