Could someone explain the colours?

Hi

It's probably something quite simple but could someone possibly explain something I've noticed? I've taken a screenshot of a model I'm printing, if you look at it from below most of it is showing as light blue which I presume means its touching the bed, a few bits of red where it needs support. The bit I don't understand is the dark blue section, can anyone help?

 

Thanks

@eightbitghost, if you could Use "File | Save Project" and post the 3mf file here then someone can take a look.

 

Taking a SWAG I'd guess the bottom isn't quite flat.  Have you tried the rotation tool "lay flat" option?

The dark blue bits extend under the buildplate. They are effectively cut off when slicing.

Thanks for the help, I had used the lay flat option but that didn't Eem to make any difference. To fix it I rotated the model in the shapr software so that Cura didn't have to rotate it and it got rid of the dark blue.
