What is the best way to create a relative color algorithm for data in an HTML table?

Question

I have an HTML data table and I want to emulate the Excel Color scale for conditional formatting , so it highlights the relative value in this data set.

The HTML table simply crosses out the list of rows, and for each row I have a value (0 - 300), and I want it to color the background of the row of the table based on this algorithm, so I assume that it will need to generate a name or HTML color value for each input number

Any help where to start here?
