Question

I’m generating some charts that need a hex string for the colors.

Example:

<dataseries name='ford' color='FF00FF' /> 

I’m creating these dynamically, so I would like to generate the hex code for each dataseries randomly.

What is the best way to do this?

Answer 1

Easiest way is to use String.Format and use the hexadecimal format for the argument.

var random = new Random(); var color = String.Format('#{0:X6}', random.Next(0x1000000)); // = '#A197B9'
