Change the 2nd default color of the signing / initial block

When adding a 2nd signer, I find the color of the 1st signing block (light blue) is very similar to the 2nd color of the 2nd signing block (light aqua). Can this be changed??  It is mind numbing that a professional signing platform would use 2 colors that are so similar. 

Trying to backtrack through a document to figure out if I’ve double dragged the same initial block or the 2nd signer shouldn’t be this difficult…

Use a DIFFERENT color; orange, purple, red … whatever… it’s a line of code.

Option 2: allow the admin to choose the signer block color.
