Sartorial Re-invention

I have decided to re-invent my wardrobe after an astonishing observation on my part, no on the part of my wife. I have realised that my favourite colour is not blue as I had earlier assumed, but yellow. A yellow shirt or tie somehow does wonders for me: I become much more relaxed, more engaging and outgoing, more resourceful, more productive. In one word the yellow colour brings out the best in me instead of the mostly white and blue shirts I am used to wearing to work.
I guess it has to do with how people react to me in the colour as supposed to how I relate to them. I don't know for sure, perhaps yellow is the colour that attracts people to me the most.
To function optimally and enhance my personal brand I will be donning something with a yellow streak in it more and more to see where it takes me.
This all begun last year when my better half commented on the fact that I was 'glowing' in the yellow shirt I wore to a Church service. Since then I have noticed how positive the responses have been form colleagues and friends whenever I don a good yellow fabric.
Having grown up in Ghana, I am used to the diverse manner we clothe ourselves, however the type of corporate culture in South Africa being formal as it is, has not really allowed me much space to incorporate my idea of sartorial excellence in the way I 'adorn' myself for work here.
There are however certain colours I will never be found dead in:
1. no red shirts for formal occasions. To me it does show a lack of a serous disposition. Nincompoopish is what I prefer to call it.
2. no pink colours. Many men are embracing this colour, but call me conservative or what you like, the colour does not do it for me, period.
3. no green socks or suits, please. It is so otherworldly on me, make me look like an alien.
4. no white suits.They are too showy for my liking! I am not an entertainer nor am I a magician.
I don't want to take myself so seriously though, so I am ready to listen to your good suggestions on what is in vogue for a dark-skinned chap like myself in this season.
My eyes are wide opened to read your personal experiences.
