[ANSTHRLD] Contrast Check

[Gary Koehler]

Good afternoon all!
 
I am designing a new device for myself, but am unsure if it will run into contrast problems. The blazon is: "Gules, on a dance counter-ermine, a plate".
 
Is the dance as blazoned useable, or would it still be considered color-on-color due to contrast? If it is illegal, could it be fixed by fimbriating the dance in a metal?
 
Thank you, as always, for your help!
