Sometimes the colors can change a lot depending on the lighting when the picture is taken. Would you say the colors in the pics match what it looks like in person? I want to say its a Pastel with something else. The dark areas are faded in spots. It kinda reminds me of a Pastel Yellow Belly.
I can tell you 100% that there isnt any pastel or yellowbelly in that snake. As for mocha, thats a pretty subtle morph so you would need better pics if you want an accurate answer.
Your lighting is not the greatest but you can only go by what you bought it as for now.
I am not familiar with the mochas and to be honest I don't see anything special with the photos on WOBP.
Most look like really clean normal to me.
Now the Cinny Mocha and the Pastel Mocha are super nice but still the base does nothing for me.
