Use Colour Schemes in your JS

If you are making a custom chart, you can pick your colours using this API to make sure it is consistent with all your other diagrams! I also highly recommend adding a figure legend to inform your users and keep things consistent!

// The colors variable is a simple array of HEX Codes.

// Retrieve the user set colour scheme...

// Categorical: Maximize contrast for showing different categories.
var colors = tripalD3.getColorScheme("categorical");

// Quantitative: for a gradient.
var colors = tripalD3.getColorScheme("quantitative");
