Wanting to get to know my frogs better

[outbackfrogs]

Hi everyone,
I have 2 frogs that I was told are both green tree frogs but they look completely different to each other and google isn’t helping me identify them. Is there anyone here who could help me please? One is the typical green colour and size but with completely black eyes and the other is slightly smaller and changes from dark olive green with white spots to brown with white spots and the eyes are golden with black slits. She can change colour multiple times in a day where the typical green one never changes colour. They’re both the coolest things! So fascinating and friendly.
