Digi-negs - blocking color/curve for Gum

Hello,

I¹m just getting started with Digi negs. For Cyanotype at least a greenish
neg printed on an Epson R220 has worked very well. I¹d like to try gum
(dichromate). I use the sun to print. Any preferred blocking colors for this
process? Also can anyone share their PS curves?

I¹m amazed at how well this faint green negative actually works.

Thanks in advance.

Max
