Colour wheel?
Blue flag indicates "consistent onsite presence"
Green flag indicates "regular onsite presence"
Yellow flag indicates "some onsite presence"
Red flag indicates "limited onsite presence"
I can see Blue + Yellow = Green - regular ~ some consistent onsite presence
so Purple = Red + Blue ~ consistent limited onsite presence (as in never :)
I suppose Orange means some limited onsite presence, or just the bloke delivering the tea room supplies* in a high vis vest.
Its a shit show here! No kidding.
Next it will be daily ink stamps on wrist and gold stars at the end of the week, and of course the naughty step. :).
*Doubtless the cheapest granulated instant instant coffee/rat droppings and teabags (resembling something even more gross) that corporate procurement could locate.
