Welcome to the community.
I have to agree, your Crestie is not a Halloween or a tricolour.
It’s a lovely dark base harlequin.
@lumpy I’m very impressed with your answer 
I agree with you completely.
With regards to portholes on a Halloween, yes it’s not decided upon. However portholes are not a colour, it’s pigmentation that was unable to form colour while in the egg. So I agree they can be on Halloween (others may disagree) other then portholes a Halloween will only have 2 colours… Orange and dark base, this includes the tail.
Tricolour Cresties will have three clear colours along the side (laterals), this does not include portholes or white spots. Which I cannot see in the pics, but if you have more suffer pics we can double check if you would like?
