Purple Lustre? Pink Lustre? Copper Lustre? What is my bowl?

Hello everyone - I've always loved this color trim but never have known quite what to call it. The item is a shallow bowl. 1 1/4" high and about 7 3/4" across. No markings of any kind. First time I've ever found a piece in decent shape. Does anyone know what this decoration would be called and an approximate age of production? Thanks much!
Don

Thank you, Martin! I'm surprised it's that old. Really looks almost brand new!

Reaching way back inro the little gray cells...isn't that color known as "mulberry" in china parlance?

 

Interesting article on bat printing. I had not heard of it. Thank you.

However, the question is what color of lustre.

Pink Lustre
