Yeah, each morph has certain things that distinguish it, and sometimes it's more than just one thing. Like an albino might be almost exclusively the color with a normal pattern, but a cinnamon has both the odd color AND the different patterning.
The more genes in a snake, the more difficult it can be to distinguish all of the existing genes. Then you have massive variations inside of a single morph, where say a cinnamon can be vividly different in color and pattern from a normal OR it could be very close to a normal in color but the pattern might give it away. Bananas can be super bright or fairly dull... depending on the individual snake. So you could get a cinn-banana that ends up super bright or fairly dull... but the pattern should be the telltale clue.
And also, hatchlings after the first shed tend to be the most eye catching of colors... although some animals tend to begin fading/darkening immediately with every shed after that.
