Dartington Pottery plates - name of designs?

I don’t know if I should be posting this here or the Dartington thread.
I bought 2 dinner plates together, one with a “modernist” design and a painted Dartington mark on the reverse.
The other has red splodges on front and back which I think are red hearts which have mostly not taken well. No mark on that one but plate size etc is the same.
Are these designs known - with names, or are they one-off playful pieces or trials?
Any help appreciated as even tho’ Dartington is just down the road, I’ve not handled enough of their work.
Thanks, as ever.

They look like trial pieces. I’d expect the second one to have a lot more decoration, so presumably they were just testing the red glaze; maybe for the poppy pattern

I thought the red marks were similar to the red on the poppy pattern too. Thanks.
