What color would these two produce?

Black harlequin and Broken blue otter.

Is there a good rabbit color calculator online somewhere? There are fantastic calculators that help color guessing for horses and goats, but the couple I've found for bunnies do not seem to work (as in, the website isn't working)

This is my favorite rabbit color calculator.

Black otter and broken black otter are the most likely. Because of the darker shading on the harlequin's face its likely self based so castor isnt as likely. If the otter carries self you might get blacks and broken blacks; if its carries harlie or non extension you might get harlie or tri. The harlie carries dilute you might get blue otter... honestly almost any color is possible out of this pair

The had mostly broken, appeared to be broken black, broken blue and broken something brown. One blue solid and one really neat looking what appeared to be blue harlequin. But something happened to the nest, shes a first time momma, I think she got up while they were feeding because they were all over in the nest box and a few had already frozen when I found them
