Spaghetti squash or is it ?

I’m growing 3 spaghetti squash plants. They’re doing very well. Lots of squash growing on them some are going to be big. But I seem to have 2 different types growing.

   

The pale one is what I’ve grown before. Seeds all from same packet and brought earlier this year. I think from Mr F but I’ll have to check to be 100%. 

Any thoughts? Are the darker squash spaghetti?
