The Baidu logo contains a paw print in the middle in blue. Surrounding it, left and right, is bright red lettering. The logo is in two languages: English and Chinese. Red and blue are primary colours. Blue tends to recede and red tends to come towards the viewer.
I’m interested in the paw print in the middle. I presume that it is the paw print from a forepaw. We don’t know whether it’s a dog paw print or a cat paw print. I’m also presuming that it is either one or the other. It has four toes. The domestic cat has four toes on the forepaw unless they are polydactyl (more than the usual number of toes due to a genetic mutation).
Dogs typically have five toes on their front paws and four toes on their hind paws but, as for cats, there are exceptions.
Therefore, anatomically speaking, the Baidu logo includes the paw print of a cat. If that’s true I’m happy 🙂 .
I suspect that the designers chose four toes because it looks better. The choice was simply made on aesthetic principles. I don’t think they were figuring out whether they were drawing the paw print of a cat or dog. It is symbolic of a paw print.
I suspect that they favoured the dog because dogs are known to be good trackers due to their incredible sense of smell although cats have a great sense of smell too. And as dogs can track objects over many miles with great accuracy the logo is appropriate for a search engine. With search engines you attempt to find the information that you are looking for in a huge pool of many hundreds of millions of websites.
A website about logos informs me that the colour red of the Baidu logo is close to the Hex color #DE0F17. The blue paw print is in the colour #2529D8. The centre lettering is in white as is the background. It’s a good logo with meaning behind it.
