No, no in July it is not Blue+White+Red, it is more like Yellow, Green and a dotted Red on White.
Part 1) Yellow
As my team of top designers was not not available to explain to me the depper values of this colour, I’ll have to speculate. A least one person did admit Yellow is a fetish for him, saying „I get up in the morning for Yellow.“ First sounds like a sad story of a fanatic, but on second thought, don’t we all go up in the morning for Yellow, I mean go the toilet? Maybe I’m wrong and he meant his cup of tea? If that person would be a proper Belgian, than it is clear, „Yellow“ would have just been a cover name for a Leffe Blond or another lighter beer.
The Yellow Jersey actually was the first attempt of highly visible cycling clothing and a milestone in cycling safety. These days with reflective materials and fluorescence pigments all countries abounded the yellow jersey, well all except one little country on the European continent: France.
Some who did wear the Yellow Jersey claim it gives wings and has magic forces. For further details please refer to “Henry Potter, The impact of yellow clothing on modern witch craft” or have a look at Asterix&Obelix. If there is indeed a magic spell on the Yellow Jersey, than this might be the reason for the trouble between ASO and UCI, as UCI might try to ban the Yellow Jersey! (Watch out for illegal spiritual doping methods being the next hot topic.)
There was the open question: Can a Belgian wear Yellow? Simple answer: Yes, he can, being Eddy Merckx. Members of “Here come the Belgians” should limit the amount of yellow on the jersey to less than 50% of the visible surface area. Say, if we would drop that skinny guy in a chicken suit on an uphill, that would earn us a 3 a.m. visit from the doping control. So stay calm - do not overdo it.
