Exactly, so if Nike had of spent 10 seconds and decided that a pink and black dot was to be their logo and still marketed themselves the same way etc. and had the same products etc. they would still be where they are today.
Yep but they couldn't have used a pink and black dot for their logo. Look at their logo on any product - it's a brilliant shape that can go as small and large as needed, and still be recognisable as Nike.
It can be a white swoosh on a dark background, or a black swoosh on a light background and you can still see it clearly. It can be embroidered, work on a tv ad, or any medium they need it on. Thats why its a brilliant logo.
If the owner of Nike had come to any designer to say they had an idea for a pink and black dot, the designer would probably say that was a bad idea because
• 2 dots look stationary and don't represent speed, the nike logo currently gives an impression of movement and momentum
• its not recognisable at a distance
• when it goes down to a small size then people won't see it properly
• if you have it on a patterned sports shirt you won't see it
• a lot of other logos have dots and circles so it wont stand out
• a lot of technology companies use dots and circle so people might mistake it for that industry
• other companies have two dots (eg Mastercard)
• if its two-colour it will cost you more to use it on products (eg you'll need two colours for printing, two threads for embroidering it on runners)
• if its appearing in a grey-scale ad in a newspaper page, then the logo will just look like a black and grey dot, and won't look as strong or recognisable
• the swoosh logo can be put in any colour and still works. if you have a red football shirt and put a pink dot on it it will clash.
Off the top of my head, that's just a handful of reasons why two colour dots wouldn't work. designers are paid to sit down and go through all these problems that most clients aren't aware of fully.
