The different colors are fun to look at.

There's a bunch of different groups in which varieties (the specific colors) are organized. The varieties in a group tend to have some genetic relation. Broken is its own group for spotted versions of every other variety. Tortoise is a variety in the shaded group (shaded rabbits tend to have darker points).
But there's some exceptions to all of this, like pointed white rabbits (I think they're in their own group and I don't know if they are genetically similar to shadeds) and English spots, which are a breed that only exists in what would otherwise be called broken, but they aren't called broken (although they're the genetic equivalent of a broken).
Some breeds are recognized in broken and some art. There's different standards describing where the spots on a broken should be, which varies depending on the breed (and on some breeds it's more specific than others).

Here's a solid tortoise of a different breed (but the color should be the same with English lops and Holland lops).

Then here's a broken tortoise, like your little guy (but a bigger rabbit XD). [link]
Another broken tortoise (a velveteen lop) [link]
Not to be mistaken for red or broken red (which doesn't have darker extremities) [link]

Here's the closest thing to a calico. It's a tricolor: [link]
The solid version of a tricolor is a harlequin (only the Japanese variety of harlequin).
