Notes:

It is not possible to make the QR code a specific CMYK color value however instead of a named html color, you can use the Hex representation of the color instead:

100/81/13/1 is equivalent to  #0030DC

so

qrforecolor=darkblue qrbackcolor=white

would be

qrforecolor=#0030DC qrbackcolor=#000000

They are several online sites that do the conversion from CMYK to Hex. example: https://www.ginifab.com/feeds/pms/cmyk_to_rgb.php
