Sail numbering

[H'portLaserer]

I have a new sail that needs numbers. My Laser is only 5 digits (98079) and all the numbering instructions I can find only discuss 6 digit sails (first 2 digits red and last 4 blue/black). Can anyone tell me whether to make the first 1 or 2 digits red on this old 5 digit boat? I hear it only matters for international events but i'd like to get it right. thanks

The 9 should be red, the 8079 blue or black.

Here's the section from the class rules:
Sails purchased after 1st June 1993 and new sails stamped “New Numbers” shall have numbers that are clearly visible with the last four digits of the number in one dark, distinctive colour or black and any preceding numbers in a different, contrasting, distinctive colour (red is recommended)
