So you can see in the table above that, if you were designing a website about learning French by proxy – like this site – for instance then you would use the code #c0c0c0 when using the colour in your code. The metallic tone of silver makes it a very popular choice for web sites as it can also be subtly adjusted.
For instance you can make it more metallic which makes the site almost glitter and stand out. For a more conservative site you could ignore the metallic elements and push silver towards the greyish tone of polished silver.
