The “Heart” on JonBenets palm

[AddieBoo]

Hope everyone has had a blessed Christmas!

I am baffled on what exactly is drawn on the palm of Jon Benets right palm. Historically it has been called a heart but cannot see a heart shape from pictures posted online.
Can y’all point me in the right direction to see “heart shape”
It looks like there is something else drawn additionally in a different shade of ink?
What were the forensics on the ink?

Thank you Sleuths!!

Apparently its was just a partial heart drawn in red biro, the same way lots of other little girls do. She had done it before
